Two cases of a 66-year-old housewife and a 52-year-old male technologist with pulmonar y atypical mycobacteriosis were reported. At first two cases were treated as cavitated pulmonary tuberculosis, but cultures of sputum gave a negative Niacin test. They died with complication of pneumonia and general weakness.
Two cases revealed similar histopathological findings of secondary pulmonary tuberculosis at autopsy; that is large cavitated lesions communicated with bronchi, epithelioid cell granuloma and acid fast bacilli. Epithelioid cell granuloma was also found in the regional lymph nodes. Atypical mycobacteria was cultured from lung tissues at autopsy (One by M. Kansasii and the other by M. Intracellulare).
