Thompson L D R, Heffess C S 2000 Renal cell carcinoma to the pancreas in surgical pathology material. Adsay N V, Zamboni G 2004 Paraduodenal pancreatitis: a clinicopathologically distinct entity unifying "cystic dystrophy of heterotopic pancreas", "para-duodenal wall cyst", and "groove pancreatitis". A novel member of the family of lesions characterized by the presence of perivascular epithelioid cells. The first criterion indicates that the microscopic morphology of papillary adenoma resembles that of papillary renal cell carcinoma, including lesions with both type 1 and type 2 characteristics. Larger ones are more worrisome because they have demonstrated a greater capacity for growth and may have the potential for metastasis. The third criterion reflects that no convincing evidence exists that very small tumors of those other cell types are not small carcinomas. Similar lesions frequently develop in patients receiving long-term hemodialysis and have been reported in up to 33% of patients with acquired renal cystic disease. Xipell9 found a strong correlation between tobacco smoking and the presence of papillary adenomas; this also was observed by Bennington. Macroscopic Appearances Papillary adenomas appear to the naked eye as wellcircumscribed, yellow to grayish white nodules in the renal cortex. Most occur just below the renal capsule, but ones that are invisible from the cortical surface are fairly common. The smallest ones usually are spherical, but larger ones sometimes are roughly conical with a wedgeshaped appearance in sections cut at right angles to the cortical surface. An association with scars in the renal cortex has been asserted but is controversial. In most papillary adenomas, the cytoplasm is scant and pale, amphophilic to basophilic. Occasionally it is slightly more voluminous and appears clear or filled with minute vacuoles. Less frequently, the cytoplasm is voluminous and eosinophilic, resembling type 2 papillary renal cell carcinoma. Immunohistochemistry, Ultrastructure, and Special Studies Almost all papillary adenomas react with antibodies to epithelial membrane antigen and low molecular weight cytokeratin, and a majority react with antibody to high molecular weight cytokeratin. Papillary adenomas frequently have gains of chromosomes 7 and 17 and loss of the Y chromosome typical of papillary renal cell carcinoma. A striking spoke and wheel appearance on radiography was at first thought to be diagnostic of oncocytoma, but greater experience has indicated that this is not specific, because renal cell carcinomas may have similar appearances. The tumor cannot reliably be distinguished before surgery from renal cell carcinoma by imaging or biopsy. However, several patients have had multicentric or bilateral tumors, and conservative operations have been successful when performed for these reasons. Macroscopic Appearances the most characteristic feature of renal oncocytoma is its brown color. Many oncocytomas have central zones of whitish stroma that may connect with the periphery. Occasional tumors exhibit foci of hemorrhage, but necrosis is rare and often can be related to extrinsic factors. Generally, the presence of gross necrosis or hemorrhage suggests that extra caution be exercised in making the diagnosis of oncocytoma.

Yolk Sac Tumor (Endodermal Sinus Tumor) Yolk sac tumor191 may rarely involve the lower genital tract birth control pills how do they work cheap 3.03mg drospirenone with mastercard, being more common in the vagina than the cervix birth control for women 8 months discount 3.03 mg drospirenone with amex. Tumors are typically polypoid birth control questionnaire buy drospirenone in india, and patients usually present with abnormal vaginal bleeding. Cervical yolk sac tumors have a similar histologic appearance to those that occur in the ovary (see Chapter 13A). They most often involve the posterior endocervical canal and are usually discovered incidentally in hysterectomy specimens in middleaged women. These lesions are usually not detectable by clinical examination, but can have a blue black gross appearance. Foci of stromal melanocytes have been identified in up to 29% of cervix uteri in which step sections were examined, suggesting that stromal den dritic melanocytes are more common in this location than is often appreciated. Mature Cystic Teratoma Rare examples of mature teratoma have been described to occur in the cervix, typically presenting as a polypoid mass that histologically is composed of endodermal, mesodermal, and ectodermal components. Patients usually present with abnormal bleeding (menometrorrhagia, postcoital, or postmenopausal bleeding), and the tumors usually attenuate or ulcerate the overlying mucosa. Gran ulocytic sarcoma involving the female genital tract has the same morphologic characteristics and immunophe notypic profile as its counterpart in extramedullary tissues elsewhere (see Chapter 22). J Pediatr 121: 307311 Malignant Melanoma Primary malignant melanoma of the cervix182184 is extremely rare, with approximately 30 cases reported in the literature, some of which are not well documented. The mean patient age is in the sixth decade, and they usually present with abnormal vaginal bleeding. Clinical examination generally reveals an exophytic friable mass that may be pigmented in appearance, having a gray, blue, or black coloration, or may be amelanotic. Tumors have a similar histologic appearance to melanoma elsewhere, having a spindled and/or epithelioid appearance; clear cell variants mimicking clear cell carcinoma may also 834 Cervix 25.

The mortality rate is high; among 18 cases with follow-up birth control rash purchase drospirenone 3.03mg online, 13 have died of disease at 7 months to 10 birth control pills las vegas purchase generic drospirenone canada. On the other hand birth control for women 24 discount drospirenone 3.03 mg without prescription, for encapsulated tumors, marked female predominance is seen (M/F = 2: 21). Among 21 patients with follow-up, 19 were alive and well at 2 to 22 years, one was alive with disease at 4 years, and one died of unrelated disease. The columnar cell variant of papillary carcinoma is characterized by mixed papillary, complex glandular, cribriform, and solid patterns. The papillae and glands are lined by tall columnar cells with pseudostratified hyperchromatic oval or elongated nuclei. Stated simply, columnar cell carcinoma is histologically reminiscent of colorectal carcinoma or endometrioid adenocarcinoma, whereas tall cell papillary carcinoma looks more like conventional papillary carcinoma. One problem is that the nuclear features do not fit the basic definition of papillary carcinoma. It is formed predominantly by cells with abundant eosinophilic granular cytoplasm caused by accumulation of mitochondria. This example shows cytoplasmic clearing, a fairly common feature of this variant and reminiscent of early secretory endometrium. Rare cases of papillary carcinoma exhibit extensive cytoplasmic clearing, usually because of accumulation of glycogen. In those cases with admixed oxyphilic tumor cells, the clear cell change may be confined to the apical portion of the cells and results from ballooning of mitochondria. This refers to tumors with greater than 50% of their area composed of large follicles. The cells that line the macrofollicles are attenuated and thus may not display the characteristic nuclear features of papillary carcinoma. The tumor cells are cuboidal or columnar, with the cells oriented perpendicularly in the long, straight trabeculae. Univariate and multivariate analysis have shown this variant to be associated with a poorer prognosis. The tumor cells have abundant eosinophilic granular cytoplasm, but they are not "tall. Rare cases of papillary carcinoma resemble Warthin tumor of the salivary gland by virtue of a papillary pattern and a rich lymphoplasmacytic infiltrate in the cores of the papillae. The cells that cover the papillae often have an oxyphilic appearance and can be tall. A, Papillary projections covered by eosinophilic lining cells and having a lymphoid stroma produce an appearance reminiscent of Warthin tumor of the salivary gland. A, the tumor is composed mostly of large follicles distended with colloid, mimicking colloid nodule. B, the characteristic nuclear features may not be evident in the large follicles but are better seen in the small follicles (left upper field). The tumor is often circumscribed or even encapsulated, with or without capsular and vascular invasion. The neoplasm can potentially be mistaken for tall cell papillary carcinoma, columnar cell carcinoma, or hyalinizing trabecular adenoma or carcinoma. A, It typically shows mixed architectural features, with intricate blending of cribriform structures, variably fused follicles, and papillae.
