A case of bronchial gland mixed tumor of the salivary gland type is reported with cytological, histopathological and microcytofluorometric findings. A 57-year-old woman consulted the hospital because her chest X-ray film showed a tumor shadow in the left upper lobe of the lung. Bronchofiberscopy showed a polypoid tumor that occluded the orifice of the left B<SUP>3</SUP>b+c. Left upper lobectomy was performed on suspicion of bronchial gland tumor.<BR>Cytologically, most cancer cells showed slight atypia. The cytoplasm was abundant, and was stained lightly by light green. The N/C ratio was decreased and the nucleus showed a fine reticular chromatin pattern. On the other hand, some cancer cells that had dense cytoplasm with irregular polyhedral contours resembled squamous metaplastic cells.<BR>Histologically both squamous metaplastic cells and foamy cells were seen. Proliferation of cartilaginous and spindle cells was also seen in parts.<BR>We studied the nuclear DNA content by microcytofluorometry. The DNA histogram showed the typical diploid pattern. This study indicates that this tumor might be classed as a low grade malignancy.
