胸腺瘤的诊断在外检工作中一直采用经典分型方法,即上皮细胞型、淋巴细胞型和混合细胞型。本文回顾性研究胸腺瘤的免疫组化标记发现,上皮细胞型中有非上皮性的类型,淋巴细胞犁中有粘膜相关淋巴瘤的存在。因此胸腺瘤的分类需要重新认识,这对明确诊断、选择治疗与判断预后都极为重要。本组分析了20例胸腺瘤的免疫组化和病理形态,现报告如下。材料与方法本文收集本院外科手术切除的胸腺瘤资料 The diagnosis of thymoma has been performed using classical typing methods in epidemiological studies, namely epithelial cell type, lymphocyte type, and mixed cell type. In this article, a retrospective study of thymoma immunohistochemical markers revealed non-epithelial types in epithelial cell types and the presence of mucosa-associated lymphoma in lymphocyte plows. Therefore, the classification of thymoma needs to be re-understood, which is extremely important for definite diagnosis, selection of treatment and prognosis. This group analyzed 20 cases of thymoma immunohistochemical and pathological morphology, the report is as follows. Materials and Methods This article collected surgical thymoma data from this hospital
