Six patients with multisystem paracoccidioidomycosis proven by serology and culture or smear were treated with relatively brief courses of intravenous miconazole. Two had relapsed following prior therapy; 6 had active pulmonary, 4 laryngeal, 2 oropharyngeal, 2 lymphoid, and 1 abdominal disease. Paracoccidioides brasiliensis was highly susceptible to miconazole in vitro; minimal inhibitory concentration was ⩽0.001 µg/ml. Clinical examination showed a prompt and objective response in all patients, confirmed by smear or culture and X-rays; in 4/6 serological response was shown. Side effects were minor. Two patients relapsed 3–5 mo after therapy; another had a rise in antibody 6 mo after therapy and was given maintenance oral sulfa. One remains in remission 7 mo after treatment; two given oral sulfa after response to miconazole remain in remission 4–6 mo after treatment. Paracoccidioidomycosis responds well to miconazole, but longer courses may be needed to prevent relapse.
