Mucormycosis: a rare complication of an amputation

Mucormycosis is a rare but serious opportunistic fungal infection. Several clinical forms have been described, including cutaneous localization that is frequently associated with soft tissue trauma or burns. We report a case of cutaneous mucormycosis in a diabetic patient with severe occlusive arterial disease. The diagnosis was made early with mold growth on an amputation wound and the presence of nonseptate hyphae on direct microscopic examination, later identified on culture as Lichtheimia ramosa. Aggressive treatment, including the control of underlying diseases, systemic and local amphotericin B, and extensive surgical debridement permitted successful outcomes.
