Ovarian carcinosarcoma, which is also known as a malignant mixed mullerian tumor (MMMT) of the ovary, is a rare, aggressive cancer of the ovary with two distinct characteristic cancer types i.e carcinoma and sarcoma. Primary ovarian sarcomas occur as pure sarcomas or mixed mullerian tumors (MMTs). Ovarian sarcoma is one of the least common gynecologic malignancy, constituting approximately 1% of all ovarian malignancies. Prognosis is generally poor, and the 5-year survival rate of patients with ovarian sarcoma is approximately 28.2%. Most of the women are asymptomatic, when present, symptoms may include, pain in the abdomen or pelvic area, bloating or swelling of the abdomen, quickly feeling full when eating, other digestive problems. An elevated concentration of CA-125 in serum is seen in some patients of ovarian sarcoma. Biopsy is the study of choice. Findings on MRI suggestive of ovarian sarcoma include the following. Surgery is the mainstay of treatment for ovarian sarcoma.Among all chemotherapeutic regimens that are being used to treat ovarian sarcoma, they are divided into two groups like platinum containing regimens and non-platinum regimens. Cisplatin, carboplatin are commonly used.
There is limited information available about the historical perspective of ovarian sarcoma
The staging of [malignancy name] is based on the [staging system].
OR
There is no established system for the staging of [malignancy name].

The exact causes of ovarian sarcoma have not been identified.
On the basis of age of onset, vaginal discharge, and constitutional symptoms, ovarian cancer must be differentiated from tubo-ovarian abscess, ectopic pregnancy, hydrosalpinx, salpingitis, fallopian tube carcinoma, uterine leiomyoma, choriocarcinoma, leiomyosarcoma, pregnancy, appendiceal abscess, appendiceal neoplasm, diverticular abscess, colorectal cancer, pelvic kidney, advanced bladder cancer, and retroperitoneal sarcoma.
