Omental cryptococcoma. An unusual presentation of cryptococcosis.

A case of an omental cryptococcal granuloma, believed to be the first reported, presented as an abdominal mass in a 29-year-old man. An exploratory laparotomy revealed a soft, 8-cm lesion in the omentum. Pathologic examination showed this to be a cryptococcal granuloma containing masses of budding, encapsulated yeasts. Aggregates of eosinophils were also noted. This case is unusual in both site (as cryptococcosis tends to localize in the central nervous system) and size.
