Malignant leiomyomas are tumors that develop in the muscle tissue of the uterus and other organs. Malignant leukomyomas are rare but dangerous cancers, most of which lead to rapid death. They can occur anywhere in the body where there is muscle tissue.
Malignant leiomyomas usually arise in the uterus, ovaries, intestines or stomachs, and they affect women of any age. Mature women are at high risk of developing leiomyomas because this type of cancer often occurs in conjunction with diseases that lead to thickening of the uterine lining. Such diseases include uterine fibroids, endometriosis, cervical cancer or perimetry. The development of malignant leiomas may be related to heredity. A common term describing malignant leiomas is leiomyosarcoma. Leiomyosarcoma takes second place in the structure of neoplasms after rhabdomyosarcoma. In recent years, for the first time, information has appeared about leiomyosarcoma of the mammary gland and liver, which is associated with changes in its functions in the body. Classic symptoms of leiomosarcomas are the presence of a soft exophytic node similar to a neoplasm in the abdominal cavity, the presence of symptoms of leakage of the contents of the leiomas, and a non-healing ulcerative defect. Less commonly, leiomyosarca is an incidental finding.
