摘要 目的探讨伴有脂肪瘤分化室管膜瘤的临床病理学特征。方法对1例伴有脂肪瘤分化室管膜瘤行免疫组化SP法染色、PAS染色及网状纤维染色,并复习相关文献。结果镜下见肿瘤组织中除具有典型室管膜瘤结构和血管周围假菊形团外,还有多少不等、成片或散在的脂肪细胞。免疫表型:S-100、GFAP、EMA广泛强阳性,CK、NF均阴性。Ki-67增殖指数较低(<2%),部分可达20%以上。特殊染色:PAS染色脂肪样细胞阴性,脂肪染色阳性。电镜下可见室管膜细胞典型结构。结论伴有脂肪瘤分化室管膜瘤在室管膜瘤结构基础上可见大量脂肪细胞,需与黄色瘤型室管膜瘤及伴有脂肪分化的其它颅内肿瘤鉴别。光镜观察结合免疫表型、特殊染色可资鉴别。
