黏液表皮样癌(mucoepidermoid carcinoma,MEC)是儿童与年轻人中最常见的涎腺来源的恶性肿瘤,男女比例约为3∶2.经典的MEC由黏液细胞、表皮样细胞及中间细胞按照不同比例组成,除经典的3种细胞成分外还存在一些少见亚型,其中透明细胞亚型是指肿瘤中透明细胞的比例超过其他3种经典型细胞成分的亚型.分子遗传学方面,多数MEC存在CRTC1/MAML2基因融合.本文报道1例发生于儿童腭部黏膜的透明细胞型中分化MEC.
Clear Cell Variant of Mucoepidermoid Carcinoma of Salivary Gland in Children:A Case Report
Mucoepidermoid carcinoma(MEC)is the most common malignant tumor of salivary gland origin in children and young adults,with a male-to-female ratio of approximately 3∶2.Classical MEC consists of mucous cells,epidermoid cells,and mesenchymal cells in various proportions,and there are some rare subtypes in addition to the classical three cellular components,among which,the clear-cell subtype is the one in which the percentage of clear cells in the tumor exceeds that of the other three classic cellular components.In terms of molecular genetics,most mucoepidermoid carcinomas have a CRTC1/MAML2 gene fusion.In this article,we report a case of clear cell type moderately differentiated mucoepidermoid carcinoma occurring in the palatal mucosa of a child,in order to im-prove the diagnostic ability of this type of disease in the future,and to reduce the occurrence of misdiagnosis and un-derdiagnosis.
