摘要 精囊腺混合性上皮间质肿瘤(mixed epithelial-stromal tumor,MEST),是一种非常罕见的原发于精囊具有间质成分和良性上皮成分的双相性肿瘤。本例为56岁男性,影像提示前列腺左后上方最大径约4 cm占位性病变伴出血,精囊腺来源肿物可能。组织学形态显示肿瘤由多量大小不等的囊腔组成,囊腔衬覆单层或多层立方上皮,局灶可见乳头状内折,细胞无明显异型;囊腔间为弥漫增生的短梭形细胞,细胞密度较高,未见明确核分裂象。免疫组织化学显示上皮细胞PAX8、细胞角蛋白(CK)7阳性,间质细胞雌激素受体(ER)、孕激素受体(PR)阳性,CD34、平滑肌肌动蛋白(SMA)部分阳性,NKX3.1阴性,Ki-67阳性指数约为1%~2%。此病临床和影像诊断困难,确诊需要病理检查,现报道1例精囊腺低级别MEST,旨在提高对本病的认识,减少误诊。
