Primary ovarian Wilms' tumor

A case of extrarenal Wilms' tumor presenting as an ovarian mass in a woman 56 years of age is described. Histologically, glomeruloid and tubular structures were identified within nests of undifferentiated epithelium. No teratomatous components were encountered. A review of the literature found three other reports of Wilms' tumor occurring in the female genital tract. This case represents the oldest patient with extrarenal Wilms' tumor in the literature.

Papillae formation in parathyroid adenoma. A source of possible diagnostic error

Parathyroid adenomas, the most common cause of hyperparathyroidism, display diverse histologic patterns. The majority of adenomas form solid masses or show nodular, trabecular, and acinar patterns. In a four-year review of data on 103 surgically resected parathyroid adenomas, we encountered only a single case that showed papillae formation. We report this case to illustrate occurrence of this unusual histologic pattern that might create a diagnostic problem.

[Occurrence of pleural mesothelioma. Chronic fibrosing pleurisy and calcified pleural plaques in Turkey in relation with environmental pollution by mineral fibers (author's transl)]

The incidence of pleural mesothelioma (PM), chronic fibrosing pleurisy (CFP) and calcified pleural plaques (CPP) has been studied in Anatolia (Turkey) in relation with environmental pollution by mineral fibers: 1) In central Anatolia, where asbestos deposits have been described, the frequency of CFP and CPP was in the range 2-25%; several cases of PM have been encountered. 2) One area (Cappadoce) is free of asbestos, but contains another kind of mineral fiber: zeolite. In this area, an outbreak of PM has been described in some villages. Among the 600 inhabitants of Karain, 28 cases of PM occurred for the period January 1975-June 1979.
