Ms. Kiran Kaur Indian Journal of Modern Research and Reviews 2584-184X 2 9 2024 September Rare Presentation of Non-Gestational Choriocarcinoma Ovary with Vaginal Metastasis- Case Report 01-03 Journal Article 2024 09 14 Background: Ovarian choriocarcinoma is an infrequent entity of ovarian cancer. It is classified as gestational (GOC)and non-gestational ovarian choriocarcinoma (NGOC). NGOC is divided into two types and mixed. The incidence of GOC-1 is 369,000,000, while NGOC contributes to about 0.6% of malignant ovarian germ cell tumors. Case Report: 22-year-old nulligravida presented to ER with c/o heavy bleeding PV for 1 month with unstable vitals, CT scan 11/9/23- s/o? large sub serosal fibroid of size 10x7cm/? adnexal mass with vaginal metastasis. She was taken up for laparotomy to achieve hemostasis and intraoperatively 9*8cm solid, multinodular dark red mass replacing almost the entire right ovary with dense adhesions to the fallopian tube, uterus, and lateral pelvic wall, proceeded for adhesiolysis and right salpingo-oophorectomy. HPE S/O NGOC. Conclusion: NCGO mostly spreads to the adjacent organs, and often commonly metastasizes to distant organs, considered to have a poor prognosis compared to GCO. ;
