心脏恶性纤维组织细胞瘤病理分析
夏 燕 ,孟宪 良,封 扬
[摘要]tl的:探讨心脏原发性恶性纤维组织细胞瘤的病理诊断和临床病理特点。方法:对 1例心脏原发性恶性纤维组织细胞
瘤进行光镜观察和免疫组织化学标记,并复习相关文献。结果:肿瘤位于左心房后壁,呈 3个分叶,长径 2.0~4.5em。镜检
见瘤细胞大多为梭形 ,呈束状排列 ,可见黏液样基质 ,薄壁血管丰富,间质见显著慢性炎细胞浸润。免疫表型:瘤细胞 vimentin
(卅),CD68(+),Ki一67(++,50%),SMA(+,灶性),S一100蛋 白(+),CD34(一),desmin(一)。结论 :心脏恶性纤维组织细胞
瘤临床易误诊为心房黏液瘤 ,要依据形态特征及免疫表型方可确诊。本瘤恶性程度高,易复发,预后不佳。
