This paper reports a case with an undifferentiated carcinoma of the esophagus which primarily developed symptoms due to metastatic lesions. The case was a 59-year-old woman with a primary manifestation of an abdominal mass and with subsequent dysphagia. A protruding lesion with ulceration was found at the lower third of the thoracic esophagus by endoscopic examination and was histologically proved to be an undifferentiated carcinoma by biopsy. The abdominal mass was initially thought to be due to metastasis to an abdominal lymph node based on the diagnosis image finding at admission, but it was consequently found by autopsy to be a metastatic tumor in the liver. Therefore, undifferentiated carcinoma of the esophagus should be take into account for differential diagnosis of an abdominal mass.
本文报告一例食管未分化癌病例，该病例主要因转移灶出现症状。患者为一名59岁女性，最初表现为腹部肿块，随后出现吞咽困难。经内镜检查发现胸段食管下三分之一处有一伴有溃疡的突出病变，活检组织学证实为未分化癌。根据入院时的诊断影像结果，最初认为腹部肿块是由于腹部淋巴结转移所致，但尸检结果显示为肝脏转移瘤。因此，在鉴别诊断腹部肿块时应考虑食管未分化癌。
