The liver and biliary tree are common sites of initial metastasis for many primary tumors. However, we recently encountered a patient who presented with biliary-tree tumor encasement as a first metastasis from squamous carcinoma of the anus.
To our knowledge, this has not been previously described in the literature.
As obstructive jaundice is a relatively common presenting sign in the emergency room and in general surgical clinics, we thus recommend early consideration of metastatic disease as a differential diagnosis in patients post-chemoradiotherapy for anal carcinoma who present with obstructive jaundice.
肝脏和胆道系统是许多原发性肿瘤初始转移的常见部位。然而，我们最近遇到了一位患者，他最初的转移部位是肛门鳞癌，表现为胆道肿瘤包绕。
据我们所知，这在文献中尚未有过描述。
由于阻塞性黄疸是急诊室和普通外科诊所中较为常见的表现，因此我们建议对接受肛门癌放化疗后出现阻塞性黄疸的患者，及早考虑转移疾病作为鉴别诊断。
