摘要 目的探讨Merkel细胞癌的临床病理学特征、组织来源、发病原因、诊断和鉴别诊断、治疗及预后。方法观察2例Merkel细胞癌患者的组织病理学特点和免疫组织化学结果,分析其临床特点并复习相关文献。结果光镜下肿瘤主要位于皮肤真皮层,细胞呈圆形、卵圆形或梭形,大小形态较一致,染色质呈细颗粒状,癌细胞排列呈巢索状或弥漫片状,核分裂象多见;免疫组织化学染色显示CK20和神经内分泌标记阳性;其组织来源与发病原因尚不明确,有待进一步的研究。结论 Merkel细胞癌是一种皮肤原发的高度恶性神经内分泌肿瘤,掌握其临床病理学及免疫组织化学特征对该病的诊断和鉴别诊断具有重要意义,对其生物学行为的最新研究可能为治疗和预后提供新的依据。
