A 18 year old man presented with a left sided testicular and left sided abdominal mass on routine physical examination. There was evidence of liver and lung metastases on workup, and tumor markers (HCG, AFP, LDH) were markedly elevated in the thousands. A left ureteral stent was placed for left sided hydronephrosis. He underwent a left radical orchiectomy through a groin incision. Pathological diagnosis was non-seminomatous germ cell tumor containing yolk sac, embryonal and immature teratomatous elements. He underwent four cycles of BEP (bleomycin, etoposide, cis-platin) over a four month period. The tumor markers returned to normal and the liver and lung metastases disappeared. The abdominal tumor shrank to 2/3 its original size.
