Gastrointestinal Involvement of Testicular Germ Cell Tumor: A Case Report and Literature Review

Testicular germ cell tumors (GCT) are the commonest solid tumors in young men. Typical presentation is with painless scrotal swelling; however, symptoms related to complications or metastasis may be the initial presentation. Gastrointestinal (GI) metastasis is seen in about 5% of patients with germ cell tumors and presentation is commonly with GI bleed. It is important to have GCT as a differential diagnosis of GI bleed in young men presenting with unexplained anemia as direct questioning about scrotal swelling and genital examination when appropriate will guide further investigation and facilitate prompt diagnosis. We present a case of a 26-year-old man with testicular germ cell tumor and severe anemia secondary to extension and perforation of duodenum by retroperitoneal metastasis and a review of the literature on the gastrointestinal manifestations of testicular germ cell tumors.
