title: [Extragonadal germ tumor].
abstract: Extragonadal primary tumors are uncommon and account for 3 to 5% of all germ cells neoplasias. Preferentially found in middle line structures, such tumors are frequently in an advanced stage when diagnosed. Differentiation between primary extragonadal tumors and metastasis of testicular primary tumors is essential, but may be difficult in many instances.
