Fusarium spp. are emergent opportunistic moulds capable of producing life-threatening diseases, usually in immunocompromised hosts. When they infect immunocompetent patients, they usually cause localized diseases. We describe here a case of cutaneous fusariosis in a patient with a medical history of diabetes mellitus and non-Hodgkin's lymphoma who presented with two painful lesions on her left leg. The diagnosis was made on the basis of histopathological findings and skin biopsy culture. The lesions resolved after treatment with oral itraconazole. Cutaneous fusariosis manifests clinically as lesions that can be grouped into a few clinical patterns, and should always be considered in the differential diagnosis of necrotic cutaneous lesions.
