[Acinic cell tumor of the bronchial gland]

The patient was a 29-year-old male with a history of recurrent pulmonary infection for the past two years. Bronchoscopy showed complete obstruction of the left sixth bronchus by a submucosal tumor. Biopsy of the tumor revealed clear cell neoplasia suggesting bronchial gland origin. Left sixth segmentectomy was done. Grossly, the tumor was 1.5 cm in diameter, solid, yellowish white in color, round in shape and protruding into the lumen and covered by the bronchial mucosa. The lung tissue and mediastinal lymph nodes were free of tumors. Histologically, the tumor consisted of sheets of clear or granular basophilic cells. Mucicarmine-negative, diastase-resistant PAS positive granules were evident in the tumor cells. Immunohistochemical stain of amylase (salivary gland type) was positive in the tumor cells. Multiple psammoma bodies were present. Histological diagnosis was acinic cell tumor of the bronchial gland. The patient is alive and well one year after removal of the tumor.
