Granulosa cell tumor
The granulosa cell tumor of the ovary is classified as a sex-cord stromal tumor by
pathologists. These tumors are the most common ovarian tumors which produce estrogen,
leading to symptoms and signs of estrogen excess such as endometrial hyperplasia.
Occasionally, these tumors may produce androgens leading to virilization. These tumors all
have malignant potential and cases of recurrence or metastases 20-30 years after initial
diagnoses have been described. |
