Hairy cell leukemia and mucormycosis. Treatment with alpha-2 interferon.

Right maxillary sinus mucormycosis developed in a 45-year-old patient with hairy cell leukemia and pancytopenia. The patient recovered with surgical debridement, amphotericin therapy, and institution of alpha-2 interferon as therapy for his hairy cell leukemia. This may be the first case of the use of alpha-2-interferon therapy in a patient with documented systemic fungal infection and hairy cell leukemia and a rare example of recovery from this infection in a hematologic malignancy.
