[Burned out testicular tumor].

OBJECTIVE

Extragonadal germ cell tumor is a rare condition. The present study reports an additional case of this uncommon disease.

METHODS/RESULTS: A 24-year-old male with retroperitoneal disease and a testicular lesion detected by ultrasonography is described. Histopathological analysis of the orchiectomy specimen disclosed a 'burned out' tumor. The anatomopathological features of this tumor type are discussed.

CONCLUSION

Extragonadal germ cell tumor is a rare condition. It derives from the germ cells that exist in the gonad and is located in every anatomical region but the gonad itself. Ultrasonography must be performed if an extragonadal germ cell tumor is suspected.
