摘要 目的:探讨垂体细胞瘤的临床病理学特征及诊断要点。方法复习5例垂体细胞瘤的临床资料、影像学、组织学及免疫组化结果,并结合文献探讨其诊断及鉴别诊断。结果5例垂体细胞瘤中女性3例,男性2例,年龄22-49岁,3例为体检时或偶然发现,头颅CT和MIR示鞍区占位。镜下见瘤细胞长梭形、短梭形,胞核卵圆形,束状、交织状排列,部分细胞多形性,核分裂象罕见。免疫表型:肿瘤均表达vi-mentin、S-100、TTF-1,Ki-67增殖指数<2%,部分表达EMA、GFAP,不表达垂体激素。结论垂体细胞瘤是起源于鞍区和鞍上区神经垂体细胞的罕见肿瘤,生长较缓慢,属于WHOⅠ级,实际工作中需与毛细胞型星形细胞瘤、梭形嗜酸细胞瘤和脑膜瘤等进行鉴别。
