目的探讨腮腺基底细胞瘤(Basal Cell Adenoma,BCA)的病理学及免疫组化表型特征。方法回顾性分析6例BCA病理学特征,用S-P法进行免疫组化研究。结果 BCA主要是由腺样细胞构成的上皮源性肿瘤;免疫组化AE1/3、CK5/6、SMA均表达阳性。结论 BCA是一种少见腮腺的上皮源性肿瘤;瘤体主要由腺样细胞构成,免疫组化上皮细胞分化标志物多呈阳性,具有比较特征性的病理及免疫组化表现。
Objective To investigate the pathological and immunohistochemical characteristics of Basal Cell Adenoma (BCA). Methods Six cases of pathological features of BCA were retrospectively analyzed. Immunohistochemistry was performed using S-P method. Results BCA was mainly epithelial tumor composed of adenoid cells. The expression of AE1 / 3, CK5 / 6 and SMA were all positive. Conclusion BCA is a rare parotid gland epithelial tumor. The tumor mainly consists of adenoid cells. Immunohistochemical epithelial cell differentiation markers are mostly positive and have characteristic pathological and immunohistochemical findings.
