Metastatic seminoma presenting as flank pain.

Seminoma is the most common single histological sub-type of testicular carcinoma. Patients usually present with a painless lump and stage I disease. We describe a case of an incidental meta-static seminoma in a 28-year-old man post-renal trauma with a dramatically elevated ß-human chorionic gonadotropin (ßHCG). His ßHCG level has returned to normal post-orchidectomy and chemotherapy.
