摘要 目的探讨局限型肉瘤样恶性胸膜间皮瘤临床病理特点、诊断和鉴别诊断。方法对1例纵膈内肺膜下局限型肉瘤样恶性间皮瘤的临床资料、组织学特征、免疫组化进行回顾性分析,并复习相关文献。结果胸部CT示右上肺病灶,大小8 cm×7.4 cm×7 cm,境界清楚。术中见肿瘤位于右上肺脏层胸膜下。镜下示纤维肉瘤样改变,细胞异型明显,核分裂象多见,局部可见坏死等,未见明确上皮样结构。免疫表型:CKpan、CK5/6、Calrentin、vimentin、WT-1均阳性,Ki-67增殖指数>20%,CEA、TTF-1、D2-40、SMA、S-100均阴性。结论局限型肉瘤样恶性胸膜间皮瘤的诊断需结合临床和影像学资料,依据组织病理学和免疫表型综合判断,需与发生于胸膜的肉瘤样肿瘤相鉴别。
