title: Seminoma presenting as renal mass, inferior vena caval thrombus, and regressed testicular mass.
abstract: Testicular cancer is the most common malignancy of men aged 15-40. Metastatic spread classically begins with involvement of the retroperitoneal lymph nodes, with metastases to the liver, lung, bone, and brain representing advancing disease. Treatment is based on pathologic analysis of the excised testicle and presence of elevated tumor markers. We report a case of a 34-year-old male presenting with back pain who was found to have a right renal mass with tumor extension into the inferior vena cava. Subsequent biopsy was consistent with seminoma. We review this rare case and discuss the literature regarding its diagnosis and management.
