补充资料:卵巢成人型粒层细胞瘤
卵巢成人型粒层细胞瘤
除幼年型粒层细胞瘤以外的颗粒细胞瘤称为卵巢成人型粒层细胞瘤,占全部卵巢肿瘤的1%~2%,占颗粒细胞瘤的95%。1/3发生在生育年龄妇女,其余发生在绝经后,约5%可发生在月经初潮前的女孩。肿瘤95%为单侧性,体积差别较大,平均直径12cm。大多数肿瘤为实性或囊实性,表面光滑,圆形,卵圆形或分叶状,常常有包膜。质地硬,韧或软。切面实性部分可为灰色、黄色或白色,有灶性出血或坏死。囊性区含水样,血性或胶样液。小部分颗粒细胞瘤主要为囊性,大体上如囊腺瘤。镜下见瘤细胞小,通常为多角形、圆形,也可为梭形,含少量淡伊红染色的胞浆,细胞边界不清楚。细胞核圆形,卵圆形或梭形,核膜清楚,典型者可见纵行核沟,使瘤细胞核有咖啡豆样外观。常有一小核仁,核染色质一般较致密,也可较疏松,甚至为空泡状。瘤细胞位于梭形间质细胞间,可排列成多种形式,如小梁型、缎带型、岛状型、圆柱瘤型、微滤泡型;巨滤泡型、弥漫型等,常常以数种类型混合存在,有时也可以一种类型排列为主。其中微滤泡型是指单层粒层细胞以非一致方向排列成小环状,中央为致密的嗜伊红性物质,其内可含皱缩的核或核碎片,此为卵巢成人型颗粒细胞瘤组织学特征之一,称CallExner小体。该肿瘤的一般临床表现为非特异性的腹部包块,内分泌紊乱的症状如月经不规则,月经过多,闭经,或二者兼有之。治疗原则同卵巢幼年型颗粒细胞瘤。老年患者应行全子宫及双附件切除术。预后比卵巢幼年型颗粒细胞瘤稍差。10年存活率为88%~93%。
