阑尾杯状细胞类癌3例临床病理分析

目的探讨阑尾杯状细胞类癌的临床病理特点及免疫表型。方法对3例阑尾杯状细胞类癌进行组织学观察及免疫组化分析,并分析其临床资料。结果 3例阑尾杯状细胞类癌均为男性,平均年龄54岁,临床表现均为右下腹痛,术前均诊断为急性阑尾炎,肿瘤均位于阑尾尖部,平均直径为8.5 mm,组织学上由形态一致的杯状细胞形成巢状结构,呈浸润性生长,3例均侵及阑尾浆膜层。免疫表型：Syn及CgA均呈阳性,CK、NSE为局灶性阳性,CEA均为弥漫性阳性。随访至2010年6月均为无瘤生存。结论阑尾杯状细胞类癌是1种组织形态和免疫表型上具有外分泌和内分泌双重特点的肿瘤,较经典类癌更具侵袭性,需与腺癌鉴别。
