摘要 目的探讨肺部血管瘤样纤维组织细胞瘤(angiomatoid fibrous histiocytoma,AFH)的临床病理学特点、诊断、鉴别诊断及预后。方法对1例AFH进行光镜观察、免疫组化染色并复习相关文献,分析其临床病理学特点。结果肿瘤周围可见不完整纤维性假包膜,小淋巴细胞和浆细胞不等量浸润,在肿瘤周围形成淋巴组织套;肿瘤内见散在无内皮衬附的假血管腔结构;肿瘤细胞呈漩涡状、束状、席纹状排列,核梭形至卵圆形,有一定异型性,罕见核分裂象和坏死。免疫表型:肿瘤细胞EMA、CD68、CD99、Calponin和vimentin均呈弥漫阳性,Ki-67增殖指数为5%。病理诊断:右肺上叶肿物AFH。结论发生于肺部的AFH较罕见,易误诊,需与炎性肌纤维母细胞肿瘤、滤泡树突细胞肉瘤、梭形细胞癌和异位脑膜瘤鉴别,AFH预后良好。
