A malignant mixed Müllerian tumor, also known as malignant mixed mesodermal tumor (MMMT) is a cancer found in the uterus, the ovaries, the fallopian tubes and other parts of the body that contains both carcinomatous (epithelial tissue) and sarcomatous (connective tissue) components.
Adenosarcoma (also Müllerian adenosarcoma) is a rare malignant tumor that occurs in women of all age groups, but most commonly post-menopause.Adenosarcoma arises from mesenchymal tissue and has a mixture of the tumoral components of an adenoma, a tumor of epithelial origin, and a sarcoma, a tumor originating from connective tissue.
As ovarian cancer is rarely symptomatic until an advanced stage, [42] regular pre-emptive screening is a particularly important tool for avoiding the late stage at which most patients present. However, A 2011 US study found that transvaginal ultrasound and cancer marker CA125 screening did not reduce ovarian cancer mortality. [ 43 ]
A serous tumour is a neoplasm that typically has papillary to solid formations of tumor cells with crowded nuclei, and which typically arises on the modified Müllerian-derived serous membranes that surround the ovaries in females.
It is an uncommon form of endometrial cancer that typically arises in postmenopausal women. It is typically diagnosed on endometrial biopsy , prompted by post-menopausal bleeding . Unlike the more common low-grade endometrioid endometrial adenocarcinoma, uterine serous carcinoma does not develop from endometrial hyperplasia and is not hormone ...
Uterine adenosarcoma have, by definition, a malignant stroma and benign glandular elements. The World Health Organization (WHO) criteria have a mitotic rate cut point; however, this is often disregarded, as bland-appearing tumours with a low mitotic rate are known to metastasize occasionally.
Prognosis and treatment is the same as for the most common type of ovarian cancer, which is epithelial ovarian cancer. [6] [7] The median survival of primary peritoneal carcinomas is usually shorter by 2–6 months time when compared with serous ovarian cancer. Studies show median survival varies between 11.3 and 17.8 months.
Müllerian duct anomalies are those structural anomalies caused by errors in Müllerian duct development as an embryo forms. Factors contributing to them include genetics and maternal exposure to substances that interfere with fetal development.
