Abstract

Abstract: The seromucinous glands of the bronchi can give rise to tumors resembling those of the salivary glands. Basal cell adenoma (BCA) has not been reported in salivary gland-type tumors of the lung. Here, we report a case of an 86-year-old Asian man who suffered from pneumonia in the left upper lung field that may be associated with an endobronchial tumor occluding B 1 + 2 a + b. The bronchoscopic biopsy of the tumor revealed that the basaloid cells, which constituted a major component of the tumor and were positive for p40/p63 immunohistochemistry, exhibited a cord-like structure. The Ki-67 ( MKI67 ) staining was less than 1% positive. These findings suggest that the endobronchial tumor was BCA of the lung, which caused obstructive pneumonia in the patient.
