Small bowel metastases from a testicular choriocarcinoma revealed by gastrointestinal bleeding: a case report.

Testicular germ cell tumors are the most common cancers in young men. In most cases, patients may present a painless testicular swelling. However, in 10% the presentation is variable and related to site of metastasis and complications. Clinically apparent gastrointestinal involvement was seen in 5% of cases and dominates by gastrointestinal bleeding. We report a case of testicular choriocarcinoma involving the small intestine revealed by melena and complicated by acute intussusception.
