Sex cord stromal tumors of the testis

Last revised by Jeremy Jones on 20 Sep 2021

Sex cord stromal tumors of the testis are uncommon testicular neoplasms. Although ~90% of these tumors are benign, they cannot be differentiated from testicular malignancies on imaging, and are therefore usually discovered after orchiectomy.


Uncommon testicular neoplasms with mildly increased incidence in pediatric patients

  • 4% of all testicular neoplasms
  • 11%, if <12 years old.


These tumors arise from cells that form the sex cords (Sertoli cells) and those that form the testicular stroma (Leydig cells).
