Ovarian cancer. Light micrograph (LM) of a section of a granulosa cell tumour of the ovary. Granulosa cell tumor (GCT) of the ovary is an uncommon neoplasm that represents 2% to 5% of all ovarian cancers. As the name implies, GCT is derived from the granulosa cell, a hormonally active component of the ovarian stroma that is responsible for estradiol (female sex hormone) production. Granulosa cell tumors of the ovary are considered as low grade malignancies with a relatively more favorable prognosis compared with much more commonly encountered epithelial ovarian tumors.
