Ectopic prostatic tissue in the uterine cervix.

This is the first reported case of ectopic prostatic tissue in the uterine cervix, diagnosed in a 38-year-old woman. A cluster of benign prostatic glands with cribriform and papillary patterns and focal squamous metaplasia occupied the superficial endocervical stroma. The glands were immunoreactive for prostatic specific antigen and prostatic specific acid phosphatase.

[Whipple's disease. A case report and review of the literature].

A 19 year-old man had a clinical history of volvulus, ascites and abdominal pain; later, malabsorption syndrome was recognized. Jejunal biopsies obtained by endoscopic technique show changes consistent in Whipple's disease with minimal intestinal involvement and atrophy. This case report is the first in which volvulus, minimal intestinal involvement and malabsorption syndrome were recognized together.

Oat cell carcinoma of the gallbladder.

Among 448 malignant epithelial tumors of the gallbladder, 19 were classified as oat cell carcinomas. Seventeen cases occurred in elderly women. Eighteen of the patients had cholelithiasis.

The ultrastructure of gallbladder carcinoma.

Nine malignant epithelial tumors of the gallbladder were examined electron microscopically. The tumors included the following subtypes: well-differentiated adenocarcinoma, signet ring cell carcinoma, adenosquamous carcinoma, and oat cell carcinoma. Well-differentiated adenocarcinomas recapitulated the ultrastructure of the normal surface epithelium of the gallbladder.

Multiple endocrine neoplasia. Pituitary adenoma, multicentric papillary thyroid carcinoma, bilateral carotid body paraganglioma, parathyroid hyperplasia, gastric leiomyoma, and systemic amyloidosis.

Multiple endocrine neoplasia in a 70-year-old woman are described. The findings include a nonfunctioning pituitary adenoma, a multicentric papillary thyroid carcinoma, bilateral carotid body paragangliomas, parathyroid hyperplasia, gastric leiomyoma and systemic amyloidosis. A study of the kindred revealed that two family members, a daughter and a granddaughter, have clinical and radiographic evidence of pituitary tumors and bilateral carotid body paragangliomas, suggesting that this may represent a genetically determined syndrome inherited as an autosomal dominant.
