支气管粘液表皮样癌是一种少见肿瘤,国外文献报告90余例。本文报告3例。本病大部分属低度恶性,手术切除彻底,预后较好。因本病无特征性临床表现,术前易误诊。因此凡有无法解释的长期呼吸道症状的中青年男性患者,建议作纤维支气管镜检查,以提高早期诊断及治愈率. Bronchial mucoepidermoid carcinoma is a rare tumor, and more than 90 cases have been reported in foreign literature. This article reports 3 cases. Most of the disease is low-grade, with complete surgical resection and good prognosis. Due to the absence of characteristic clinical manifestations of this disease, it is easy to misdiagnose before surgery. Therefore, in young and middle-aged men with unexplained long-term respiratory symptoms, fiberoptic bronchoscopy is recommended to improve early diagnosis and cure rate.
