Sex cord stromal tumours of the testis

Sex cord stromal tumours of the testis are uncommon testicular neoplasms. Although ~90% of these tumours 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 paediatric patients

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


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