title: [Extragonadal germinal tumor].
abstract: OBJECTIVE
  Extragondal germ cell tumors are rare and have a high affinity for the midline structures. Herein we describe a young, male patient with a retroperitoneal primary tumor.
  
  
  RESULTS
  The unorthodox form of presentation of germ cell tumors corroborates their embryologic gonadal origin which is distant from the site of presentation.
  
  
  CONCLUSIONS
  The diagnostic algorithm, chemotherapeutic and surgical treatment guidelines utilized in the management of primary gonadal germ cell tumors with retroperitoneal involvement remain applicable in this rare form of presentation.
