摘要: 2017年世界卫生组织(WHO)内分泌系统肿瘤分类定义了零细胞腺瘤,源自腺垂体细胞,无免疫组织化学检测证实的细胞特异性激素和相关转化因子分化。该肿瘤好发于老年人,以占位效应为主。组织学形态,肿瘤呈嫌色性,亦可呈轻度嗜酸性; 肿瘤组织由圆形或多角形细胞弥漫性片状排列构成(图1),乳头状和假“菊形团”样结构相对少见,细胞异型性不明显,核分裂象罕见。免疫组织化学染色,肿瘤细胞胞质突触素(Syn)和嗜铬素A(CgA)呈阳性(图2);催乳素(PRL)、生长激素(GΗ)、促肾上腺皮质激素(ACTH)、促性腺激素、促甲状腺激素、 α亚单位及相关转化因子(如TPIT、PIT-1、SF1等)呈阴性,细胞角蛋白(CK) 可呈阴性。特殊染色高碘酸-雪夫(PAS)染色呈阴性。
