Primary cutaneous mucormycosis in a healthy young girl. Report of a case caused by Mucor hiemalis Wehmer.

We report an unusual case of primary cutaneous mucormycosis caused by Mucor hiemalis Wehmer that occurred in a healthy young girl after an insect bite. The patient had a slowly extending, indurated, erythematous, and scaling eruption on the right cheek. Histologic examination revealed granulomatous dermatitis and characteristic broad, nonseptate, pale-staining hyphae. This is the first report of an infection in a human being caused by Mucor hiemalis Wehmer. The infection was cured with intravenous amphotericin B.
