Adenoid Cystic Carcinoma Arising in the Intrapulmonary Bronchus

Abstract

A 63-year-old male was admitted to our hospital because of a coin lesion in the intrapulmonary bronchus. The patient had no symptoms such as cough or sputum. Imaging studies showed that the tumor was present in the S10b, c of the right lung. There was no metastasis or salivary gland tumor. Transbronchial tumor biopsy revealed a primary adenoid cystic carcinoma. The patient underwent a lobectomy, and has been well since the operation. This is an uncommon case of primary adenoid cystic carcinoma arising from the intrapulmonary bronchus.
