MUCOEPIDERMOID CARCINOMA の 2 症例

Abstract

Two cases of mucoepidermoid carcinoma of the bronchus were diagnosed and treated surgically. Mucoepidermoid carcinoma, especially the lowgrade intra-luminar type, is difficult to diagnose both clinically and histologically. The patients with bloody sputa and obstructive pneumonia on chest X-ray film should be carefully evaluated in consideration of the existence of intra-bronchial mucoepidermoid carcinoma. On bronchoscopic findings, mucoepidermoid carcinoma of intra-bronchial type is seen to be covered with normal bronchial mucosa, but its surface is easily bleeding. Histological diagnosis with the specimen by transbronchial biopsy is not usually conclusive, and the answer is apt to be [the proliferation of normal bronchial glands]. Total resection of the tumor is recommended, and PAS-alucian blue staining is main stay for the diagnosis.
