摘要 目的探讨胰腺实性型浆液性囊腺瘤(solid-type serous cystadenoma,SSCA)的临床病理学特征。方法观察1例罕见的胰腺SSCA,结合文献分析其病理特征及鉴别诊断。结果患者为67岁男性,体检发现胰头占位。肿瘤肉眼实性、质韧,镜下境界清楚,呈结节状或分叶状,间质富含血管;肿瘤细胞呈紧密排列的实性巢、小腺泡、小腺管,局灶或散在可见小囊腔形成;肿瘤细胞呈立方或多边形,胞质丰富透明或淡嗜酸颗粒状,核小而圆,未见明显异型性及核分裂象。免疫表型:肿瘤细胞CK7、CK19、AAT、Inhibin-α、Calponin、MUC1、NSE均阳性,Ki-67增殖指数低,神经内分泌标记CgA、Syn、CD56及其他鉴别标记均阴性。术后随访22个月,未见复发或转移。结论 SSCA是胰腺浆液性囊性肿瘤的罕见亚型,患者手术切除预后良好,最终确诊依赖于病理检查。
