A case of phaeohyphomycosis is reported in a male renal transplant
recipient with a nodular lesion in the right leg who was treated
with immunosuppressing drugs. The lesion consisted of a purulent cyst
with thick walls. The cyst was excised surgically, and the
patient did not receive any antifungal therapy. One year later
he remains well. Histological study of the lesion showed a
granulomatous reaction of epithelioid and multinucleate giant cells,
with a central area of necrosis and pus. Fontana-Masson staining
demonstrated the presence of pigmented hyphal elements. The fungus Colletotrichum crassipes was grown in different
cultures from the cyst. The in vitro inhibitory activities of eight
antifungal drugs against the isolate were tested. Clotrimazole and
UR-9825 were the most active drugs. This case represents the first
known reported infection caused by this rare species.
