[edit] Clinical presentation
Estrogens are produced by functioning tumours, and the clinical presentation depends on the patient's age.
- If the patient is postmenopausal, she usually presents with abnormal uterine bleeding.
- If the patient is of reproductive age, she would present with menometrorrhagia.
- If the patient has not undergone puberty, isosexual-pseudo-precocity may be seen.
[edit] Histology
The most characteristic gross appearance is a smooth surfaced solid and cystic lesion with the cysts filled with blood. Hemoperitoneum is an infrequent but classical presentation. A large variety of histological presentations exists, but they have two key features:
- Call-Exner bodies (granulosa cells arranged haphazardly around a space containing eosinophilic fluid); and
- Pale uniform nuclei, often with grooves
