title: Primary retroperitoneal pure yolk-sac tumor in an adult male.
abstract: Pure extragonadal tumors are rare in adult males. A 24-year-old male with an extremely high level of serum alpha-fetoprotein (32.795 ng/ml) was diagnosed by abdominal computed tomography as having a retroperitoneal tumor. A case of primary retroperitoneal pure yolk-sac tumor in an adult male is described.
