What Is Myoma Utery?

Myoma is one of the uterine tumor in pregnancy and childbirth. Myoma utery/ leiomyoma/ fibroids is a local proliferation of smooth muscle cells of the uterus. Myoma utery belonging to benign tumor to the uterus. It is firmly bounded, no capsule and is formed mainly of muscle and fibrous connective tissue elements. Shortly, myoma utery is benign mesenchimal tumor arising from uterine smooth muscle cells.

Myoma utery usually found in women of childbearing age and the frequency decreased at the age of menopause. In general, myoma utery doesn’t need therapy unless the tumor mass became large enough to interfere with other structures in the pelvic. Type of interference can be either pelvic pain or pressure which is subjected to appropriate places.

This benign tumor is responsive to the hormone estrogen. Myoma utery can grow rapidly and become giant in size during pregnancy or if exposed to estrogen. At the time of menopause, the tumors usually stop growing and may atrophy due to decreased levels of endogenous estrogen. Based on its location in the uterus myoma utery is divided into three: Submucosal myoma (below the endometrial mucosa), intramural myoma (in the muscle layer of the uterus) and subserous myoma (under the serous layer).
Myoma can grow further; it can stand out through endometrial or serous and stemmed. Sometimes attached to the omentum or mesentery of the large intestine. Some submucosal myoma pouch be stemmed in utery, protruding through cervix (Uterine Geburt). Myoma utery can experience many changes, among others: hyaline degeneration, cystic, red (hemorrhagic), calcific and sarcomatous. During pregnancy myoma growth and degeneration can cause infarction and bleeding in the tumor in 50% of pregnancies.
