Omphalokeratolith.

A 69-year-old woman presented with a firm, black umbilical mass of unknown duration. It was easily removed with a warmed otic glycerin preparation. Histologic examination showed that it contained laminated keratin, amorphous material resembling sebum, numerous terminal hairs, and scattered collections of bacteria. Moderate amounts of argentaffin staining material were detected throughout the specimen, and the black color of the lesion was probably due to melanin and oxidized lipids, much like an open comedone. The mass is appropriately called an omphalokeratolith.

Gastrointestinal dissemination of coccidioidomycosis.

An unusual case of extensive gastrointestinal involvement by the fungus Coccidioides immitis is reported in a 21-yr-old man. This unique case demonstrates the occurrence of this fungus within chylous ascites, the mesentery, and invasion of the entire length of the small bowel. Histological and cultural documentation for gastrointestinal tract involvement by C. immitis other than for the rare occurrence of peritonitis has not been previously reported. The significance of the disseminated gastrointestinal coccidioidomycosis in the setting of chylous ascites and extensive abdominal lymphatic involvement is discussed with respect to its pathogenesis and treatment.
