This report presents the case of a 66-year-old male with appendicular metastasis from hepatocellular carcinoma. He had a clinical history of right lobectomy of the liver after the diagnosis of hepatocellular carcinoma 3 years prior, and was admitted because of an asymptomatic appendiceal tumor detected by computed tomography. The appendiceal tumor was preoperatively suspected to be a recurrence of hepatocellular carcinoma, because of the patient's elevated level of serum α-fetoprotein and protein induced by vitamin K absence or antagonist II, and based on the magnetic resonance imaging findings. An appendectomy was thus performed, and the histopathological findings confirmed the diagnosis of a metastatic tumor from hepatocellular carcinoma. Appendicular metastasis is extremely rare. This is only the second case of a metastatic appendiceal tumor from hepatocellular carcinoma reported in the English literature.
本报告介绍了一例 66 岁男性阑尾转移性腺癌病例。该患者 3 年前因诊断为肝细胞癌而行右半肝切除术，因 CT 检查发现阑尾肿瘤而无症状入院。术前考虑阑尾肿瘤为肝细胞癌复发，因为患者血清 α-胎蛋白和维生素 K 拮抗剂 II 诱导蛋白水平升高，且基于磁共振成像结果。因此行阑尾切除术，组织病理学检查结果证实为肝细胞癌转移瘤。阑尾转移极为罕见。这是英文文献中仅有的第二例肝细胞癌阑尾转移瘤病例。
