支气管粘液腺腺瘤(MGAB)是一种罕见的肿瘤,文献中仅报导过41例。MGAB易与支气管的其他良性病变及起源于支气管的低度恶性粘液表皮样癌相混淆,因此正确识别这一肿瘤具有重要的临床意义。作者报导10例MGAB的临床病理、组织化学、免疫组织化学及超微结构特征,以加深临床及病理工作者对这一罕见肿瘤的认识。 材料和方法 MGAB的诊断际准如下:①起源于支气管;②肿瘤为富含粘液的囊性肿物;③含有数量不
Bronchial mucinous adenoma (MGAB) is a rare tumor, and only 41 cases have been reported in the literature. MGAB is easily confused with other benign lesions of the bronchus and low-grade malignant mucoepidermoid carcinomas originating from the bronchus. Therefore, it is of great clinical significance to correctly identify this tumor. The authors reported the clinical pathology, histochemistry, immunohistochemistry and ultrastructural features of 10 cases of MGAB in order to deepen the understanding of this rare tumor by clinicians and pathologists. Materials and Methods The diagnostic criteria for MGAB are as follows: 1 Originated from the bronchus; 2 Tumors are mucinous cystic masses; 3 Contains no quantities
