Scytalidium dimidiatum and Lecythophora hoffmannii: unusual causes of fungal infections in a patient with AIDS.

Immunocompromised patients are susceptible to infections by fungi that seldom cause disease in humans. We describe a human immunodeficiency virus-infected patient who had simultaneous infections with two fungi which are rare causes of serious infection: Lecythophora hoffmannii, causing chronic sinusitis, and Scytalidium dimidiatum, causing skin lesions, lymphangitis, and lymphadenitis. The clinical and pathologic findings are discussed.
