A 56-year-old man with bronchial asthma and diabetes was admitted with massive hemoptysis and thick-walled cavity in the right middle lung field on chest X-ray films. He had been treated with antibiotics for eight months under the diagnosis of lung abscess before his admission. After occlusion of the bronchial arteries with metallic coils, bronchofiberscopy was performed disclosing the obstruction of right B3b. Microscopic examination of bioptic material and bronchial brushing smear taken from right B3b yielded numerous broad, nonseparate hyphae. Right middle and lower lobectomy were performed under a diagnosis of chronic pulmonary mucormycosis. The patient was recovered and discharged on 55 th days after operation.
