Fatal disseminated cryptococcosis in a HIV negative elderly Indian woman--an early diagnosis by polarizing microscopy.

ABSTRACT

An elderly HIV negative woman with disseminated cryptococcosis is reported. The clinical presentation was unusual. Rapid diagnosis is possible if Maltese crosses are demonstrated on polarizing microscopy of tissue sections or smears. Cutaneous involvement in cryptococcosis is uncommon, however when present, can be a valuable and relatively easily available source of material from which Cryptococci can be demonstrated.
