Testicular germ cell tumors, though rare (1%), represent the most common neoplasm among young men. Gastrointestinal involvement from these malignancies usually presents as bowel obstruction and digestive bleeding, but their frequency is low (5%). The patterns of this involvement are: infiltration from affected retroperitoneal lymph nodes or, less frequently, by peritoneal seeding and direct hematogenous spread. Particularly, infiltration of duodenum is also rare, though its real frequency is not well defined. Moreover, the affinity for GI tract differs among the histological types of GCT, being seminomatous tumors an exceedingly unfrequent cause of duodenal infiltration. We herein present a recent case in our institution of severe anemia due to gastrointestinal bleeding in the context of giant retroperitoneal bulky metastatic mass infiltrating duodenum as first manifestation of a testicular pure seminoma.
睾丸生殖细胞肿瘤虽然罕见（1%），却是年轻男性中最常见的肿瘤。这些恶性肿瘤累及胃肠道通常表现为肠梗阻和消化道出血，但其发生率较低（5%）。这种累及的方式有：受累腹膜后淋巴结的浸润，或较少见的腹膜种植和直接血行播散。特别是十二指肠浸润也很罕见，不过其实际发生率尚不清楚。此外，胃肠道受累在不同组织学类型的生殖细胞肿瘤中存在差异，精原细胞瘤是十二指肠浸润极为罕见的原因。我们在此报告我院近期的一例病例，一名睾丸纯精原细胞瘤患者，以巨大腹膜后转移性肿块浸润十二指肠为首发表现，导致胃肠道出血，进而引发严重贫血。
