title: Ocular cryptococcosis.
abstract: We studied ocular cryptococcosis in a 59-year-old man who had received extensive chemotherapy for abdominal malignant lymphoma. Mucinous lesions containing abundant cryptococci, but no inflammatory cells, formed in the posterior choroid of the eye. Electron microscopy revealed that mucin, a filamentous substance, coated the encapsulated organisms. Except for a few degenerating ones in histiocytes, most cryptococci appeared in the extracellular space.
