Because the mechanism of action is poorly understood pain treatment center hartford hospital elavil 10 mg buy on-line, an element of trial and error is often required when developing a treatment plan pain treatment for osteoporosis purchase 25 mg elavil overnight delivery. In addition advanced pain treatment center chicago 25 mg elavil purchase overnight delivery, several adjuvant methods are available for the treatment of fibromyalgia of the cervical spine northside pain treatment center atlanta purchase elavil online. For this reason a better life pain treatment center golden valley buy 50 mg elavil fast delivery, a targeted history and physical examination, with a systematic search for trigger points and identification of a positive jump sign, must be carried out in every patient suspected of suffering from scapulocostal syndrome. The clinician must also identify coexisting psychological and behavioral abnormalities that may mask or exacerbate the symptoms associated with scapulocostal syndrome. Therefore, in patients suspected of suffering from scapulocostal syndrome, a careful evaluation to identify underlying disease processes is mandatory. Scapulocostal syndrome commonly coexists with various somatic and psychological disorders. In Atlas of pain management injection techniques, ed 2, Philadelphia, 2007, Saunders, pp 123­128. Coronal T2-weighted magnetic resonance imaging scan showing high signal at the site of the disruption (large white arrow) and an increased pennate angle (small white arrow) resulting from muscular retraction of the infraspinatus. Tendinitis and bursitis may coexist with arthritis pain, and they make the correct diagnosis more difficult. The olecranon bursa lies in the posterior aspect of the elbow joint and may become inflamed as a result of direct trauma or overuse of the joint. Bursae susceptible to the development of bursitis also exist between the insertion of the biceps and the head of the radius, as well as in the antecubital and cubital areas. Arthritis of elbow Olecranon bursa figure 37-1 Arthritis of the elbow can cause pain and functional disability during common everyday tasks. Some patients also complain of a grating or popping sensation with use of the joint, and crepitus may be present on physical examination. A total of 5 mL local anesthetic and 40 mg methylprednisolone is drawn up in a 12-mL sterile syringe. After sterile preparation of the skin overlying the posterolateral aspect of the joint, the head of the radius is identified. Just superior to the head of the radius is an indentation that represents the space between the radial head and the humerus. Less common causes of arthritis-induced elbow pain include collagen vascular diseases, infection, and Lyme disease. Acute infectious arthritis is usually accompanied by significant systemic symptoms, including fever and malaise, and should be easily recognized; treatment is with culture and antibiotics rather than injection therapy. The small focus of low signal noted at the proximal end of the ligament may represent an avulsion fragment (short arrow). The major complication of intraarticular injection of the elbow is infection, although it should be exceedingly rare if strict aseptic technique is followed. The ulnar nerve is especially susceptible to damage at the elbow, and care must be taken to avoid this structure when performing intraarticular injection. Approximately 25% of patients complain of a transient increase in pain after intraarticular injection of the elbow joint, and patients should be warned of this possibility. Coexistent bursitis and tendinitis may contribute to elbow pain and may confuse the diagnosis. Physical modalities, including local heat and gentle range-ofmotion exercises, should be introduced several days after the patient undergoes injection for elbow pain. Sellards R, Kuebrich C: the elbow: diagnosis and treatment of common injuries, Prim Care 32(1):1­16, 2005. In Atlas of pain management injection techniques, ed 2, Philadelphia, 2007, Saunders, pp 129­132. The pathophysiology of tennis elbow initially involves microtearing at the origin of the extensor carpi radialis and extensor carpi ulnaris. Secondary inflammation may become chronic as a result of continued overuse or misuse of the extensors of the forearm. Coexistent bursitis, arthritis, or gout may perpetuate the pain and disability of tennis elbow. The most common nidus of pain from tennis elbow is the bony origin of the extensor tendon of the extensor carpi radialis brevis at the anterior facet of the lateral epicondyle. Less commonly, tennis elbow pain originates from the origin of the extensor carpi radialis longus at the supracondylar crest; rarely, it originates more distally, at the point where the extensor carpi radialis brevis overlies the radial head. The olecranon bursa lies in the posterior aspect of the elbow joint and may also become inflamed (bursitis) as a result of direct trauma to the joint or its overuse. Tennis elbow occurs in individuals engaged in repetitive activities such as hand grasping. Tennis players develop tennis elbow by two different mechanisms: (1) increased pressure grip strain as a result of playing with too heavy a racket, and (2) making backhand shots with a leading shoulder and elbow rather than keeping the shoulder and elbow parallel to the net. Many patients with tennis elbow exhibit a bandlike thickening within the affected extensor tendons. Radial tunnel syndrome is caused by entrapment of the radial nerve below the elbow. With radial tunnel syndrome, the maximal tenderness to palpation is distal to the lateral epicondyle over the radial nerve, whereas with tennis elbow, the maximal tenderness to palpation is over the lateral epicondyle. Plain radiographs should be obtained in all patients who present with elbow pain to rule out joint mice and other occult bony disease. For patients who do not respond to these treatment modalities, injection of local anesthetic and steroid is a reasonable next step. A total of 1 mL local anesthetic and 40 mg methylprednisolone is drawn up in a 5-mL sterile syringe. After sterile preparation of the skin overlying the posterolateral aspect of the joint, the lateral epicondyle is identified. A, Coronal inversion recovery magnetic resonance image shows marrow edema in the lateral epicondyle (arrow) and subtle edema adjacent to the mildly thickened common extensor tendon (arrowhead). B, Radiograph shows calcific tendinitis of the common extensor tendon (arrowheads). A Velcro band placed around the extensor tendons may also help relieve the symptoms. CompliCaTionS and piTfallS the major complication associated with tennis elbow is rupture of the inflamed tendon either from repetitive trauma or from injection directly into the tendon. To prevent inflamed and previously damaged tendons from rupturing, the needle position should be confirmed to be outside the tendon before the clinician proceeds with the injection. The injection technique is safe if careful attention is paid to the clinically relevant anatomy; in particular, the ulnar nerve is susceptible to damage at the elbow. Clinical Pearls the injection technique described is extremely effective in the treatment of pain secondary to tennis elbow. Cervical radiculopathy and radial tunnel syndrome may mimic tennis elbow and must be excluded. In Atlas of pain management injection techniques, ed 3, Philadelphia, 2009, Saunders, pp 137­144. Wilhelm A: Lateral epicondylitis: review and current concepts, J Hand Surg 34(7):1358­1359, 2009. Secondary inflammation may become chronic as a result of continued overuse or misuse of the flexors of the forearm. These activities have in common repetitive flexion of the wrist and strain on the flexor tendons resulting from excessive weight or sudden arrested motion. The olecranon bursa lies in the posterior aspect of the elbow joint and may become inflamed as a result of direct trauma to the joint or its overuse. Using strict aseptic technique, a 1-inch, 25-gauge needle is inserted perpendicular to the medial epicondyle through the skin and into the subcutaneous tissue overlying the affected tendon. The needle is then removed, and a sterile pressure dressing and ice pack are applied to the injection site. In Atlas of pain management injection techniques, ed 3, Philadelphia, 2009, Saunders, pp 148­153. CompliCaTionS and piTfallS the major complications associated with this injection technique are related to trauma to the inflamed and previously damaged tendon, which may rupture if injected directly. Therefore, the needle position should be confirmed to be outside the tendon before the clinician proceeds with the injection. Proximal rupture of the tendon of the long head of the biceps tendon accounts for more than 97% of biceps tendon ruptures, whereas ruptures of the distal portion of the biceps tendon occur less than 3% of the time. Falls on a flexed and supinated elbow have also been associated with tears and rupture of the distal biceps tendon, as has abuse of anabolic steroids in athletes. The biceps muscle and proximal and distal tendons are intimately involved in shoulder and elbow function and are susceptible to trauma and to wear and tear. SignS and SympTomS In most patients, the pain of distal biceps tendon tear occurs acutely, is often quite severe, and is accompanied by a pop or snapping sound. The pain is constant and severe and is localized to the region surrounding the antecubital fossa. Patients with complete distal biceps tendon tear experience weakness of upper extremity flexion and supination. An obvious defect is palpable in the antecubital fossa in patients with complete rupture of the distal biceps tendon. A comparative study of 22 patients treated with either nonoperative management or early anatomical repair, Injury 39[7]:753­760, 2008. B, Axial image with visible hemorrhage surrounding the insertion site at the bicipital tuberosity of the proximal radius. However, coexisting bursitis or tendinitis of the elbow from overuse or misuse may confuse the diagnosis. In some clinical situations, consideration should be given to primary or secondary tumors involving the elbow. For patients who do not respond to these treatment modalities and who appear to have significant local pain in the region of the distal biceps tendon, careful injection with local anesthetic and steroid is a reasonable next step. Injection for distal biceps tendon tear is carried out by placing the patient in the sitting position with the elbow flexed to approximately 90 degrees. If intact, the distal biceps tendon is easily identified by palpation at the antecubital fossa. The previously marked point is palpated, and the distal biceps tendon or area of defect is reidentified with the gloved finger. The needle is carefully advanced at this point through the skin and subcutaneous tissues until it impinges on the distal biceps tendon or enters the area of defect. The needle is then withdrawn 1 to 2 mm out of the substance of the tendon, and the contents of the syringe are gently injected. If resistance is significant, the needle tip is probably in the substance of the tendon and should be advanced or withdrawn slightly until the injection can proceed without significant resistance. Clinical Pearls the distal biceps tendon ruptures much less commonly than the proximal long head of the biceps tendon, although the forces that can cause either end of the tendon to rupture are similar. Coexistent bursitis and arthritis may contribute to shoulder pain, thus necessitating additional treatment with more localized injection of local anesthetic and methylprednisolone. CompliCaTionS and piTfallS this injection technique is safe if careful attention is paid to the clinically relevant anatomy. The major complication of this injection technique is infection, although it should be exceedingly rare if strict aseptic technique is followed. Trauma to the distal biceps tendon from the injection itself is also a possibility. In Brukner P, Khan K, editors: Clinical sports medicine, ed 3, New York, 2006, McGraw-Hill Medical, pp 235­241. When this occurs, the result is acute, localized, medial elbow pain combined with decreased throwing accuracy and throwing distance. In addition, the findings of osteochondrosis of the humeral capitellum, osteochondritis dissecans of the humeral capitellum, osteochondritis of the radial head, hypertrophy of the ulna, traction apophysitis of the olecranon, triceps tendinitis, and mild instability of the ulnar collateral ligament complex may be observed alone or in combination with the foregoing pathologic processes. Less commonly, nerve entrapment syndromes and subluxation of the ulnar nerve can also occur (Table 41-1). The patient may note the inability to hold a coffee cup or use a hammer, and the examiner may notice reduced grip strength. Physical examination may also reveal localized tenderness along the flexor tendons at or just below the medial epicondyle. If the patient has an acute injury to the elbow, swelling and ecchymosis may be present. Increased valgus angle greater than 11 degrees in male patients and 13 degrees in female patients may also be noted. This phase begins as the foot contacts the ground and ends as the arm reaches maximal external rotation. The olecranon bursa lies in the posterior aspect of the elbow joint and may become inflamed as a result late deceleration, medial epicondylitis and, less commonly, an ulnar nerve disorder are often the cause. Pain during deceleration should alert the clinician to pay special attention to the posterior elements of the elbow because olecranon and triceps tendon abnormalities and joint mice may be the problem. Palpation of the anterior band of the ulnar collateral ligament is performed with the elbow in 70 to 90 degrees of flexion. A B Phase 1: Windup Begins with the pitcher balancing his or her weight over the rear leg, with the elbow flexed and the forward leg flexed at least 90 degrees. Phase 2: Early cocking/stride Starts with the lead leg beginning to descend toward the plate, and the two arms separate. Phase 3: Late cocking Begins when the humerus is in extreme abduction and external rotation and the elbow is flexed. The lead foot contacts the ground, the pelvis and trunk rotate, and elbow torque transfers valgus force across the elbow joint. During this phase, medial tension and lateral compression forces are applied to the elbow. Maximal external shoulder rotation occurs to release ball, with trunk rotating and the elbow rapidly extending.

They were composed entirely or almost entirely of endocervical-like epithelium; polygonal eosinophilic cells and/or foci of endometrioid and squamous differentiation were also occasionally seen pain treatment center fairbanks alaska buy elavil us. Hobnail pain treatment consultants of wny elavil 75 mg purchase visa, eosinophilic davis pain treatment center statesville nc 50 mg elavil sale, squamous shoulder pain treatment guidelines purchase elavil 75 mg line, clear treatment of neuropathic pain guidelines discount 75 mg elavil, and signet-ring cells were also present in varying proportions. Their findings did not support a category of seromucinous carcinoma but allowed reclassification of their tumors as endometrioid carcinoma with mucinous differentiation (23), low-grade serous carcinoma (3), or mucinous carcinoma (1). The admixture of one of these components within an endometrioid carcinoma adversely affects the prognosis. Surface epithelial tumors (serous, mucinous, endometrioid, clear cell) are rarely mixed with an unusual high-grade component such as hepatoid carcinoma, pulmonary-type small cell carcinoma, neuroendocrine carcinoma, or choriocarcinoma.

Synchronous involvement of both the cervix and the corpus favors secondary disease pain medication for dog bite cheap elavil 25 mg. In contrast to primary uterine lymphomas pain treatment west plains mo cheap elavil 25 mg buy, the corpus is involved as often as the cervix sports spine pain treatment center hartsdale order discount elavil online. Clinical manifestations related to the uterine involvement are often absent neck pain treatment physiotherapy buy elavil us, but in a few cases chronic neck pain treatment guidelines discount 75 mg elavil amex, there has been vaginal bleeding or discharge. The types of lymphoma are more variable than in primary uterine lymphomas with less pronounced predominance of diffuse large B-cell lymphoma. In one case of the latter that relapsed in the uterus, the recurrent tumor had a striking signet-ring cell phenotype that was absent in the primary tumor. About 20 cases of myelogenous leukemia have presented as a myeloid sarcoma within the uterus, usually in adults. The patients typically have abnormal vaginal bleeding, pain, or malignant cells in Pap smears. Cervical involvement is much more common than the corpus; we have seen a case of myeloid sarcoma presenting within an endocervical polyp. Involvement of other genital sites (vagina, vulva, parametrium, tube, ovary) has been present in about half the cases. Involvement of extragenital sites (bone marrow, lymph nodes, gastrointestinal tract) may also be found. In most patients, an absence of leukemic cells in the peripheral blood at presentation is eventually followed by acute myelogenous leukemia. Almost 90% of patients with follow-up reported in the older literature died of disease, whereas in a recent study of gynecologic myeloid sarcomas Garcia et al. Gross examination of the cervix may reveal nodules, ulcers, or large masses, often extending into the vagina or paracervical tissues. Microscopic examination reveals an appearance similar to that of myeloid sarcoma in other sites with infiltration of immature granulocytes around normal structures. Positive staining for chloracetate esterase, myeloperoxidase, and lysozyme confirms the diagnosis. The differential diagnosis includes malignant lymphoma, or occasionally, small cell carcinoma or sarcoma. Granulocytic sarcomas may be difficult or impossible to differentiate from lymphoma without the use of the special stains noted above. Uterine Involvement in Patients with Known Leukemia Leukemic cells are found in cervicovaginal smears in as many as 30% of leukemic patients. The uterine involvement is usually unassociated with symptoms, but occasionally there is abnormal bleeding, pain, a cervical mass, or combinations thereof. Left: Low-power view showing complete replacement of the stroma by the myeloid infiltrate. Center: High-power view showing the myeloid cells, some with eosinophilic granular cytoplasm. In one autopsy study, the frequency of uterine involvement was 25% (acute lymphoblastic leukemia), 11% (acute myelogenous leukemia), 14% (chronic lymphocytic leukemia), and 4% (chronic granulocytic leukemia). Rare cases of myeloma initially diagnosed on a cervical smear and/or endocervical or endometrial biopsy have been reported. Ovarian carcinomas can implant on the uterine serosa or cul-de-sac with myoinvasion. Spread to the corpus by cervical squamous cell carcinoma, adenocarcinoma, and adenosquamous carcinoma occurs by direct spread or via lymphatics, and is prognostically adverse (Amyes et al. Implantation of an endometrial adenocarcinoma on the cervical mucosa may occur (Fanning et al. Spread from an occult ovarian, tubal, or peritoneal carcinoma is occasionally detected as microscopic fragments of tumor within a curettage specimen, potentially mimicking a primary uterine carcinoma. Misdiagnosis is, of course, more likely when the extragenital carcinoma is occult. Residual endometrium with cystic atrophy is seen but it is largely replaced by the mucinous adenocarcinoma. Left: the tumor cells diffusely replace the endometrial stroma and entrap a normal endometrial gland, an appearance that can be misinterpreted as normal on low-power examination. Rare low-grade appendiceal mucinous neoplasms with pseudomyxoma peritonei may spread to the endometrium or cervix (McVeigh et al. Kumar and Hart found that the tumor was confined to the myometrium in all but one case. Rare sites of involvement include leiomyomas and endometrial polyps, including metastatic lobular breast carcinoma to endometrial polyps. Morphologic features that should suggest a possible or probable metastasis include: · A clinical background or macroscopic appearance atypical for a primary carcinoma. Rare metastatic adenocarcinomas to the uterus, especially the cervix, can have prominent mucosal involvement mimicking a primary in situ and/or invasive adenocarcinoma. Immunohistochemical markers helpful in the differential are the same as those in the differential of primary vs metastatic carcinomas involving the ovaries (Chapter 18). The cells focally have an epithelioid appearance, some showing a cord-like pattern and/or a signet-ring-like appearance.

Such foci may be misinterpreted as fibroma pain treatment herniated disc discount elavil 75 mg buy on line, particularly in the frozen section setting back pain treatment uk elavil 75 mg for sale. Feathery degeneration blue ridge pain treatment center discount elavil 50 mg buy line, a term coined to designate a particular appearance of aggregates of mucin separated by scant acellular collagenous stroma. There is a prominent solid tubular pattern resembling that of a Sertoli cell tumor. In these cases, goblet cells may form acini, microglandular patterns, nests, cords, or are singly disposed. Krukenberg tumors of colonic and biliary origin are microscopically indistinguishable from those of gastric origin and those of appendiceal origin but without the distinctive features noted above. Those from other sites, such as breast, lack the frequent intestinal-type glands of those of gastrointestinal and biliary origin. Almost all the tumors considered below are unilateral in contrast to Krukenberg tumors and the non-neoplastic lesions are not usually grossly evident. Additionally, there are a variety of microscopic differences between Krukenberg tumors and the various entities considered; only the more important are highlighted. These rare tumors are usually better differentiated both architecturally and cytologically than a Krukenberg tumor, are infrequently bilateral, and may be associated with a dermoid, or rarely an epidermoid, cyst. A poorly differentiated mucinous carcinoid likely accounts for at least some examples of so-called primary Krukenberg tumor. The presence of typical signet-ring cells excludes this diagnosis (caveat: fibromas rarely may contain mucin-negative signet-ring-like cells). This illustration shows a mostly nonspecific appearance but a few vacuoles containing targetoid eosinophilic material (best seen top center) are a clue to the diagnosis. Another common low-power appearance is a more compact growth peripherally with edema centrally, with tumor cells ramifying into the latter. The mucin-rich signet-ring cells occur singly, as small clusters, or as large, sometimes smoothly contoured, round to oval to elongated nests that may appear pseudotubular. The cytoplasm of the signet-ring cells is usually pale and vacuolated but may be basophilic or eosinophilic or contain a clear vacuole containing a central eosinophilic body. Some tumor cells have an indifferent mucin-negative appearance and may be small and deceptively benign in appearance. Rare findings include cells with abundant clear mucin-negative cytoplasm or squamous or transitional-type cells. The stroma is often edematous but may resemble a typical fibroma or less often a cellular fibroma. Ovarian cortical inclusions with a vacuolar, mucin-negative, presumably hydropic cytoplasmic change (Chapter 12). A listing of ovarian lesions that may contain signet-ring cells is presented in Table 18. The sectioned surface usually resembles that of metastatic intestinal adenocarcinoma rather than a Krukenberg tumor. Most tumors are composed of small to large glands that often have a pseudoendometrioid appearance. Occasional glands may be lined by columnar cells with pale cytoplasm or with an indifferent appearance. Signet-ring cells are usually absent, or if present, definitionally account for <10% of the tumor. The stroma usually lacks the edematous or mucoid appearance of many Krukenberg tumors. These tumors are distinguished from pseudoendometrioid metastases of other origins by clinical findings and from Krukenberg tumors with a glandular component by the absence or rarity of signet-ring cells. These ovarian tumors may be misinterpreted clinically or microscopically as primary ovarian tumors, even when there is a known colon cancer. The large to small gland pattern is in marked contrast to the appearance of a Krukenberg tumor. As with many other glandular metastases, marked maturation with a cystic pattern has resulted. Typical heterogenous morphology with small glands in a desmoplastic stroma (left) abruptly interfacing with a glandular pattern with a garland-like cribriform pattern and conspicuous dirty necrosis. The site of the primary tumors in one study was 77% in the rectosigmoid, 9% ascending colon, 9% cecum, 5% descending colon, and rarely the transverse colon. Metastatic colonic carcinomas are among the most common ovarian tumors, excluding those in the sex cord­stromal category, that are associated with estrogenic or androgenic manifestations as a result of functioning stroma. The ovarian tumors, which are bilateral in ~60% of cases, may form nonspecific solid masses, but are more often solid and cystic, sometimes being predominantly cystic. Sectioning typically reveals friable or mushy yellow, red, or gray tissue and cysts with necrotic, mucinous, clear, or bloody contents. Multiple thin-walled cysts with mucinous contents may rarely simulate a mucinous cystic neoplasm. On low power the ovarian parenchyma is usually effaced but in smaller tumors it may separate nodules of tumor that often have a prominent desmoplastic stroma. Classic garland-like arrangement of cribriform glands at the periphery of a large gland whose lumen is filled with necrotic debris. Typical colloid morphology, which is rarely a feature of primary mucinous carcinoma of the ovary. Left: Metastatic clear cell colonic adenocarcinoma mimics a primary ovarian clear cell adenocarcinoma. Right: A striking micropapillary pattern potentially mimics a serous adenocarcinoma. Endometrioid adenocarcinoma, which is in the differential diagnosis, is typically negative for both markers. Mucin-containing goblet cells may be scattered among mucin-free cells, but are often absent. Cysts lined by well-differentiated mucin-rich or flattened nonspecific epithelium are present in occasional cases. Occasionally the appearance is that of a colloid carcinoma, or, when the primary intestinal tumor (sometimes small intestinal) is of the rare clear cell type, an endometrioid carcinoma of secretory type or clear cell carcinoma is simulated. The stroma may be desmoplastic, edematous, or mucoid, and contains luteinized cells in 30% of cases. Metastatic tuMors to the ovary · 565 Differential diagnosis Primary endometrioid adenocarcinoma. Features favoring or establishing a diagnosis of metastatic colonic carcinoma include: · A known primary intestinal cancer, bilaterality, multiple nodules, dirty necrosis (particularly when extensive and associated with one or more of the other features listed here), segmental necrosis, and higher-grade nuclei and mitotic activity than in endometrioid carcinomas with similar degrees of glandular differentiation. However, metastatic intestinal carcinomas may focally have a deceptive appearance that may simulate a benign or borderline mucinous tumor. The presence of bilaterality, prominent dirty necrosis, and the immunoprofile noted above all favor or establish the latter diagnosis. The ovarian spread is usually associated with pseudomyxoma peritonei (see Chapter 20). The appendix may exhibit a mucocele or exhibit no gross abnormality; sometimes only the presence of appendiceal serosal mucin indicates an appendiceal lesion. Bilateral mucinous cystic neoplasms are seen with jelly-like material being evident on the right. The sectioned surface shows the typical jelly-like appearance of the cyst contents in these cases with a focus of more solid yellow neoplastic tissue. The ovarian parenchyma is largely replaced by pools of mucin with scant epithelium. Pools of mucin dissect through an otherwise unaltered ovarian stroma, so-called pseudomyxoma ovarii. Typical tall columnar cells are seen and have extensively retracted from the adjacent stroma. This feature is typical of metastatic low-grade appendiceal mucinous tumors but may also be seen with teratomaassociated primary tumors. These tumors exhibit a more irregular destructive growth and their glandular component varies from large cysts to small sometimes closely packed glands. Mucinous epithelial cells are usually, but not invariably, present within the ovarian and extraovarian mucin. Left: There is both parenchymal involvement and surface involvement by differentiated mucinous epithelium. Center: Note typical highly differentiated tall columnar mucinous epithelial cells. Right: Note tendency for the neoplastic epithelium to lift off from the stroma, creating a cleft-like space, a characteristic feature that is suggestive of the diagnosis. Such tumors also had immunoprofiles with a high concordance between the ovarian and appendiceal tumors. In cases of low-grade carcinoma, the differential is with other metastatic mucinous adenocarcinomas and primary mucinous carcinoma. Some such tumors may focally resemble mucinous carcinoid but have other foci that exclude carcinoid. In about one-third of them, the ovarian involvement accounts for the presenting manifestation. Although the literature might suggest otherwise, typical carcinoids and mucinous carcinoids rarely spread to the ovaries (see section on neuroendocrine tumors). Ovarian involvement by appendiceal intestinal-type adenocarcinomas and signet-ring cell adenocarcinomas has a gross appearance similar to those of metastatic intestinal adenocarcinoma and Krukenberg tumor respectively. Moderate to high-grade mucinous adenocarcinomas may have nonspecific gross features or in some cases have a gelatinous consistency. Intestinal-type adenocarcinomas have the typical pseudoendometrioid morphology of colorectal metastases. Signet-ring cell tumors have the spectrum of Krukenberg tumors, including its tubular variant. This neoplasm had a conspicuous tubular pattern, potentially mimicking a Sertoli­Leydig cell tumor. Although not evident in this image, signet-ring cells were present elsewhere (so-called tubular Krukenberg tumor). There is a conspicuous infiltrate of signet-ring cells; the primary tumor in the appendix was resected six years previously. Small aggregates of mucinous cells have a pattern reminiscent of the formations seen in mucinous carcinoid tumors. Mucinous carcinomas not of signet-ring-cell-type resemble those originating elsewhere in the intestinal tract, or even more so, the pancreas. Distinction from morphologically similar metastases originating elsewhere is largely or exclusively dependent on clinical evaluation. Distinction from primary endometrioid and mucinous carcinoma is as considered under the heading of intestinal carcinomas. Most of the primary tumors are small intestinal (usually ileum); less common sites include colon, appendix, stomach, pancreas, and bronchus. Forty percent of women in whom metastases are found at operation have carcinoid syndrome; some also have signs and symptoms referable to intestinal or ovarian involvement. As many as 25% of patients, however, may remain asymptomatic for years postoperatively, with relief of the carcinoid syndrome. Well-differentiated appendiceal neuroendocrine (carcinoid) tumors of typical type rarely spread to the ovary. The ovarian tumors, most of which are bilateral, are typically predominantly solid, with smooth or bosselated surfaces. Scattered cysts, typically filled with watery fluid, may create an appearance similar to that of a cystadenofibroma; rare tumors are predominantly cystic. Microscopic features the patterns are similar to those of primary ovarian carcinoids (Chapter 15), most commonly insular, but trabecular, mixed, and rarely, solid tubular patterns are found. Small round acini are common, often containing a homogeneous eosinophilic secretion that may undergo calcification, which is sometimes psammomatous. Occasionally, nests of tumor cells disintegrate, with the cells separating from one another. Carcinoid is the metastatic tumor that most often elicits an extensive fibromatous stromal proliferation; occasionally, the stroma is extensively hyalinized. The cytologic features of the tumors are as seen elsewhere; exceptionally the cells have abundant eosinophilic cytoplasm. An associated dermoid cyst, mucinous tumor, or struma ovarii almost by definition excludes metastatic carcinoid allowing for the rare possibility of a collision tumor. The epithelial nests of these tumors contain transitional cells with oval, pale, grooved nuclei rather than the round nuclei with stippled chromatin of carcinoids. Benign and borderline adenofibromas and endometrioid adenocarcinomas with small glands. These are distinguished from carcinoids by their differing patterns and cytologic features. In difficult cases in the foregoing differential diagnostic considerations, additional sampling and immunostaining for chromogranin, synaptophysin, peptide hormones, and serotonin will usually be diagnostic. In about 40% of cases the pancreatic tumor and ovarian metastases are synchronous and in the remainder they are asynchronous, with the pancreatic tumor usually preceding the ovarian metastases. In most cases, the primary pancreatic tumor is an adenocarcinoma of usual ductal type. However, it is rarely a mucinous cystadenocarcinoma, an acinar cell carcinoma, a neuroendocrine neoplasm, or in one case, a solid pseudopapillary tumor. Ductal-type carcinomas range from solid with multiple nodules to a large multiloculated mass mimicking a primary ovarian mucinous tumor.
