Abstract

目的: 探讨双表型肝细胞癌(DPHCC)的临床病理学特点、免疫表型、诊断和鉴别诊断。 方法: 收集福建医科大学附属协和医院病理科2018年1月至2019年12月诊断的6例DPHCC的临床病理资料及随访结果,并复习相关文献。 结果: 该组患者均为男性,年龄40~68岁(中位年龄45.5岁)。临床表现主要为右上腹闷痛,均有饮酒史及乙型肝炎病毒感染病史。影像学检查5例为肝脏单发结节,1例为肝脏多发结节。组织学表现为肿瘤细胞排列呈梁状、腺泡状及实体型,梁索间有血窦相隔,纤维间质少。6例中有4例脉管内可见瘤栓。肿瘤细胞均表达Glypican-3、CK19,6例中4例表达AFP、Heppar-1、CK7,CD34均显示肝窦毛细血管化。所有病例均经手术切除病灶,4例术后辅以化疗,术后随访6~24个月,未见复发及转移。 结论: DPHCC是肝细胞癌的一种特殊亚型,由于DPHCC与肝细胞癌的病理形态学特征相重叠,诊断DPHCC主要依靠免疫组织化学染色,而CK19可以通过各种途径参与调控DPHCC的发生、发展,因此CK19可常规应用于肝细胞癌的病理诊断借以筛查DPHCC。.
