title: [A case of endobronchial tuberculosis with peripheral mucoid impaction showing a solitary pulmonary nodular shadow].
abstract: In a 70-year-old nonsmoking, asymptomatic man, chest radiography before a operation for early gastric cancer revealed a solitary nodular shadow in the right lower lobe. Laboratory studies for bacteria and mycobacteria were negative and histological diagnosis could not be obtained. Right lower lobectomy was performed because the mass could be malignant. Histologically the right B10 was almost completely obstructed by tuberculous granuloma and the distal bronchus were dilated containing inspissated mucus. The abnormal nodular shadow was considered the obstructive mucoid impaction secondary to tuberculous bronchitis. It is quite rare that solitary nodular shadow is found in such a case of endobronchial tuberculosis.
