Abstract: 目的探讨滤泡性树突状细胞肉瘤的病理诊断及鉴别诊断.方法对1例腮腺滤泡性树突状细胞肉瘤进行HE切片、免疫组化等观察,并复习文献进行讨论.结果镜检肿瘤细胞呈梭形、卵圆形、多边形,胞质淡染,边界不清,核染色质颗粒状并见明显小核仁,可见散在核分裂象,呈片状、束状、编织状、旋涡状排列.较多淋巴细胞浸润及围绕血管形成袖套状结构.肿瘤细胞特异性地表达CD21、CD23、CD35、S-100蛋白、CD68、vimentin、EMA.结论滤泡性树突状细胞肉瘤是极少见的低中度恶性肿瘤,可出现多种组织结构,有一定的特征性,确诊需要免疫组化帮助.应与异位脑膜瘤、异位胸腺瘤、恶性纤维组织细胞瘤、淋巴上皮样癌及指突性树突状细胞肿瘤等相鉴别.
