Gastric metastasis of choriocarcinoma is rarely reported in the literature. This case report presents the case of multiple metastatic testicular choriocarcinoma mimicking gastric cancer, with melena as the initial symptom. In this case, fluorine-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) showed that the testis was the primary focus. The contribution of PET/CT is significant to primary focus detection in metastatic diseases of unknown primary origin that presented gastrointestinal bleeding. In addition to its use in staging of testicular carcinoma, PET/CT provides significant benefit in evaluating patients with increased levels of tumor markers and in detecting recurrence.
绒毛膜癌的胃转移在文献中鲜有报道。本病例报告呈现了一例以黑便为首发症状、酷似胃癌的多发性转移性睾丸绒毛膜癌病例。在此病例中，氟脱氧葡萄糖正电子发射断层扫描/计算机断层扫描（PET/CT）显示睾丸为原发灶。PET/CT对于出现胃肠道出血的不明原发灶转移疾病的原发灶检测具有重要作用。除了用于睾丸癌分期外，PET/CT在评估肿瘤标志物水平升高的患者以及检测复发方面也有显著益处。
