Metastatic choriocarcinoma is a rare nonseminomatous germ-cell tumor with a characteristic hemorrhagic tendency due to its trophoblastic origin. Gastrointestinal tube involvement is present in less than 5% of cases, and location or therapy of these lesions can be achieved by endoscopy, angiography or surgery. Despite its being a highly curable malignant disease, the occurrence of gastrointestinal bleeding worsens prognosis. We report a case of metastatic choriocarcinoma which manifested as melaena and was diagnosed by the presence of metastatic lesions in the stomach and right bowel on endoscopy.
转移性绒毛膜癌是一种罕见的非精原细胞性生殖细胞肿瘤，因其滋养层起源而具有特征性的出血倾向。胃肠道受累病例不到5%，这些病变的定位或治疗可通过内镜检查、血管造影或手术实现。尽管它是一种高度可治愈的恶性疾病，但胃肠道出血的发生会使预后恶化。我们报告一例转移性绒毛膜癌病例，该病例表现为黑便，经内镜检查发现胃和右肠存在转移性病变而确诊。
