A 74-year old man, a heavy smoker, was admitted with left side chest pain. The chest radiograph showed an abnormal shadow with a cavity in the left upper lobe. Pulmonary tuberculosis was suspected based on the chest X-ray films, carcinoma was diagnosed following cytology via fibropticbronchoscopy. Left upper lobectomy was performed. Examination of the resected specimen revealed poorly differentiated squamous cell carcinoma and granuloma with caseous necrosis in the cavity wall and Mycobacterium in the necrosis. The Mycobacterium was later revealed to be Mycobacterium avium. The patient is alive nine months after surgery with no indication of recurrence of Mycobacterium avium or lung cancer.
