Cutaneous mucormycosis resembling superficial granulomatous pyoderma in an immunocompetent host.

Primary cutaneous mucormycosis is uncommon and occurs mainly in immunosuppressed or diabetic patients or after localized trauma. We report a case of cutaneous mucormycosis in an immunocompetent man in whom no definite precipitating factors could be identified; initially, superficial granulomatous pyoderma was suspected clinically. The lesion was successfully treated with debridement, local wound care, parenteral administration of amphotericin B, and ultimately by surgical excision and split-thickness skin grafting.
