Juvenile granulosa cell tumor of ovary of child. A. A pink tumor shows cyst-like areas with occasional nodules at low power. B.

Juvenile granulosa cell tumour is an uncommon ovarian tumour in the sex cord stromal tumours group.
General
May secrete estrogen - can present with:
- Endometrial pathology, e.g. endometrial hyperplasia or endometrioid endometrial carcinoma.
- Precocious puberty.[3]
Prognosis - granulosa cell tumours (adult and juvenile):[1]
- Low-stage: 97% five year survival.
- High-stage: 67% five year survival.
Gross
- Classically solid.
Microscopic
Features:
- Microcystic spaces.
- Moderate-to-marked nuclear atypia.
- Cuboidal-to-polygonal cell in sheets or stands or cords.
- Basophilic cytoplasm.
Notes:
- Juvenile variant of GCT has more nuclear pleomorphism.
DDx:

Juvenile granulosa cell tumor of ovary of child. A. A pink tumor shows cyst-like areas with occasional nodules at low power. B. Tumor cells haphazardly spread without longitudinal grooves, with small nucleoli, in an edematous background. C. The cysts are in fact follicles, some producing, as here, the typical basophilic fluid. D. In some regions, abundant pink cytoplasm is obvious.
IHC
- Inhibin positive.[5]
- Inhibin negative in Brenner tumour.
- Calretinin +ve.
- Ki-67 <5% (12/12 cases[6]).
- CD34 -ve (0 +ve/12 cases[6]).
- Vimentin +ve (11 +ve/12 cases[6]).
- CD99 +ve.[7]
Molecular
- Currently not used for the diagnosis.
