A Case of Cutaneous Cryptococcosis Resembling Pyoderma Gangrenosum / 대한피부과학회지

ABSTRACT

Cryptococcosis is a disease caused by Cryptococcus neoformans, that most commonly affects immunosuppressed patients. Cutaneous cyptococcosis occurs in 10-15% of disseminated cases and its clinical manifestation is variable. We have presented an unusual manifestation of cutaneous cryptococcosis in a patient with iatrogenic Cushing syndrome. Clinically, the ulcers were considered to be pyoderma gangrenosum but the tissue biopsy and culture revealed cryptococcosis. This case illustrates that in making the diagnosis of pyoderma gangrenosum, one must exclude deep fungal infection.
