Chronic infection due to Fusarium oxysporum mimicking lupus vulgaris: case report and review of cutaneous involvement in fusariosis.
A 67-year-old female presented with a 20-year-old lesion involving the right ear and preauricular area mimicking tuberculous lupus. Fusarium oxysporum infection was confirmed by biopsy studies and cultures. The biopsy specimen showed an unusually extensive dermal invasion with fungal hyphae. This is an uncommon clinical presentation for Fusarium infection in a healthy patient. When referred to us, the patient had received antifungal therapy with itraconazole without any benefit. Improvement was obtained with fluconazole therapy. The spectrum of cutaneous involvement related to Fusarium spp. includes toxic reactions, colonization, superficial indolent infection, deep cutaneous or subcutaneous infections and disseminated infection.
