| Features:
| |
| * 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.

| Note:
| |
| *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.
