Primary non-gestational choriocarcinoma of ovary is a rare type of ovarian cancer that is not related to pregnancy. It is a malignant tumor that is composed of cells that are similar to those found in the placenta. Symptoms of this type of cancer may include abdominal pain, bloating, and abnormal vaginal bleeding. Treatment typically involves surgery to remove the tumor, followed by chemotherapy and/or radiation therapy.

The most common symptoms of primary non-gestational choriocarcinoma of the ovary are:

- Abdominal pain

Primary non-gestational choriocarcinoma of the ovary is a rare and aggressive form of ovarian cancer. The exact cause of this type of cancer is unknown, but it is believed to be related to genetic mutations. Other possible causes include exposure to certain chemicals, radiation, and certain viruses.

The primary treatment for primary non-gestational choriocarcinoma of the ovary is surgery. Depending on the stage of the cancer, the surgeon may remove the affected ovary, the uterus, and other nearby organs and tissues. In some cases, chemotherapy and/or radiation therapy may be recommended after surgery to reduce the risk of recurrence.
