Non-gestational choriocarcinoma of the ovary: A case report.

Non-gestational choriocarcinoma of the ovary is an extremely rare clinical condition. Very few cases of this high-grade malignancy of the ovary are reported in the literature worldwide. Given the rarity of the tumour, this disease is generally overlooked, which leads to delayed diagnosis and management. For the attending clinicians, the non-gestational choriocarcinoma of the ovary poses a diagnostic challenge due to its non-specific clinical presentations. A 16-year-old girl presented with pain in the right iliac fossa and with a positive urine pregnancy test. Despite being sexually inactive, the patient was diagnosed with an ectopic pregnancy and underwent emergency laparoscopic surgery. Six weeks later, the histopathological analysis revealed a diagnosis of non-gestational choriocarcinoma of the ovary. Further evaluations showed that her cancer had already advanced to stage IV. In this case report, the non-specific presentations of the disease, radiological features, current treatments, and possible safety strategies are discussed.
