Adult granulosa cell tumour is an ovarian tumour. It is also known as granulosa cell tumour. It dhould not be confused with the granular cell tumour.

Ideally, it should be called adult granulosa cell tumour to avoid confusion with juvenile granulosa cell tumour.



  • Normal granulosa cells convert androgen from the theca cells to estrogen and/or progesterone.[2]


  • Classically solid.



  • Classic appearance includes gland-like structures filled with acidophilic material (Call-Exner bodies).
  • Small cuboidal to polygonal cell in sheets or strands or cords.
  • Nuclear grooves.


  • There is a "10% rule" -- if less than 10% of a SCST is granulosa cells... it isn't granulosa cell tumour.
  • Juvenile variant of GCT has more nuclear pleomorphism.





Currently not used for diagnosis.
  • FOXL2 point mutation[5] seen in 86 of 89 tumours.[6]
