Abstract

BACKGROUND
Primary adenoid cystic carcinoma arising in the bronchus is an uncommon disease that is histologically and ultrastructurally identical to the salivary gland tumor of the same name and regarded as a slow growing low-grade malignancy. We examined its clinkcal characteristics. METHODS: We collected 13 Korean cases of primary adenoid cystic carcinoma arising in the bronchus including 5 cases of our own and 8 cases from the literature. RESULT: The patients ages ranged from 20 to 74. Men numbered 9 and women 4. The presenting symptoms were cough, dyspnea, and hemoptysis. The fiberoptic bronchoscopic findings were primarily hypervascular polypoid mass with a smooth surface that obstructed airway totally or near totall. There were three inoperable cases including two cases with distant metastasis to bone or cervica lymph node and one case with mediastinal invasion. The remaining 10 patients underwent surgical resection. Among them, two patients received postoperative radiotherapy. The median survival was 21 months in the 8 surgical and evaluable cases. One paient lived 13 years without recurrence. The prognosis was relatively favorable in operable cases. CONCLUSION: It was not common for primary adenoid cystic carcinoma arising in the bronchus to have distant metastasis or invasion to the mediastinum on presentation. The prognosis was relatively favorable in operable cases. It would be important to perform flexible bronchoscopy for early diagnosis and to do surgical treatment if possible
