primary non-gestational choriocarcinoma of ovary https://github.com/monarch-initiative/mondo/issues/8583 https://www.malacards.org/card/primary_non_gestational_choriocarcinoma_of_ovary 2025-04-01 MEDGEN:906353 Primary non-gestational choriocarcinoma of ovary is a rare ovarian germ cell malignant tumor, arising from primordial germ cells, usually presenting with nausea, vomiting, abdominal pain, menstrual irregularities, and characterized by fast growth pattern, metastasis to lung, liver and brain and production of human chorionic gonadotrophin (hCG). It is apparently chemoresistant and has a worse prognosis than gestational choriocarcinoma and hence should be distinguished from the latter by DNA polymorphism.
