title: Seminoma of the testis presenting as an ulcerating mass of the duodenum.
abstract: Germ cell tumors (GCT) arising in the testes secondarily involve bowel in 5% of patients (1), and such involvement is usually via extension from adjacent metastatic lymphadenopathy. While this involvement often causes obstruction and gastrointestinal bleeding, radiologic identification of bowel ulceration has not been reported. We report an unusual case of small bowel invasion and ulceration, identified on CT examination, due to adenopathy resulting from testicular carcinoma.
