Ovarian sertoli cell tumour: rare case of sex cord stromal tumour

Sertoli cell tumour is a sex cord gonadal stromal tumour of Sertoli cells. Sertoli cell ovarian tumours are very rare and constitute less than 0.5% of ovarian tumours. They differ from Sertoli leydig cell tumours in as they do not contain leydig cells or immature gonadal stroma. Most tumours are unilateral, confined to ovaries and are seen during second and third decades of life. These tumours are characterised by the presence of testicular structures that secrete androgens.
