摘要 目的通过报道罕见病膀胱浆细胞样尿路上皮癌,探讨其临床病理特征,以防误诊。方法回顾性分析1例膀胱浆细胞样尿路上皮癌的HE染色、免疫组化染色结果等临床资料,并进行文献复习。结果该例终末肉眼血尿1个月,膀胱镜检查示膀胱内右侧壁输尿管口外上方菜花样肿物2枚。病理检查:瘤细胞呈显著的浆细胞样特征,细胞呈圆形或卵圆形,胞质丰富、嗜酸性,核偏位;部分区域肿瘤细胞胞质呈空泡状,核位于一端呈印戒样。肿瘤细胞弥漫浸润膀胱黏膜固有层,多个脉管内可见癌栓。肿瘤分期T1N0M0。免疫组化:CK7、CK20、癌胚抗原(CEA)、CD138和细胞角蛋白AE1/AE3阳性,白细胞共同抗原(LCA)、Vimentin和E-cadherin均呈阴性。先后行经尿道膀胱肿瘤电切术、根治性膀胱切除术加回肠膀胱术,术后随访5个月,患者无瘤存活。结论膀胱浆细胞样尿路上皮癌具有特殊的组织病理学特征,需要与其他具有浆细胞样形态学特征的肿瘤鉴别,免疫组化有助于鉴别诊断。患者的预后与肿瘤分期密切相关。
