Abstract
Two cases of small-sized adenoid cystic carcinoma originating in the respiratory tract were reported, which could be successfully treated with tracheal or bronchial sleeve resection. Both cases had the common complaint of hemoptysis.
Case 1 was a 49-year-old man. Bronchoscopic examination revealed a samll mass on the tracheal wall at 3.5cm above the carina. Histological diagnosis of transbronchial biopsy specimens was adenoid cystic carcinoma. Four rings of the trachea were resected with end-to-end anastomosis. The tumor was 7.0×6.0mm in size.
Case 2 was a 46-year-old man. Bronchoscopic examination revealed a small mass on the mid part of the left main bronchus. Histological diagnosis of transbronchial biopsy specimens was adenoid cystic carcinoma. Three rings of the left main bronchus were resected with end-to-end anastomosis. The tumor was 6.0×5.0mm in size. Any reports of surgical cases of small-sized adenoid cystic carcinoma originating in the respiratory tract like these could not be found in the literature.
