Abstract：
This study presents a rare case of pure choriocarcinoma (PCC) with metastasis to the gastrointestinal tract in a 52-year-old male with a history of mixed germ cell tumor in remission. Despite negative oncology surveillance imaging, serum marker monitoring, and a recent colonoscopy, the patient presented with new-onset melena and dysphagia, leading to further diagnostic evaluation. Endoscopic examination revealed an ulcerated duodenal mass, and a computer tomography (CT)-guided liver biopsy confirmed metastatic PCC. This case highlights the aggressive nature of PCC and the importance of considering gastrointestinal metastasis in patients with atypical symptoms, even when in apparent remission.
摘要：
这项研究提出了一例罕见的纯绒毛膜癌（PCC）病例，该病例在52岁的男性中转移到胃肠道，患有混合生殖细胞肿瘤。尽管肿瘤监测成像阴性，血清标志物监测,和最近的结肠镜检查，患者出现新发黑便和吞咽困难,导致进一步的诊断评估。内镜检查显示十二指肠溃疡肿块，计算机断层扫描（CT）引导的肝活检证实了转移性PCC。该病例强调了PCC的侵袭性，以及在症状不典型的患者中考虑胃肠道转移的重要性。即使在明显缓解时。
