Dysgerminoma of the ovary expecting good prognosis even in advanced stages

Dysgerminoma is a rare germ cell tumor of the ovary. It constitutes about 0.5% of all ovarian malignancies. During 12 years period [1978-1989], 22 patients were treated at the National Cancer Institute, Cairo, Egypt. According to FIGO classification system, 4 patients were allocated to stage 1, 2 - stage II, 13 - stage IV.
