leiomyoma
Pronunciation: LIE-oh-my-OH-mah
Benign smooth muscle tumor of the uterus, commonly known as a fibroid, often requiring surgical management.
Full Definition
Leiomyoma, commonly referred to as uterine fibroids or myomas, are benign smooth muscle tumors that develop within the myometrium of the uterus. These tumors are classified by location: submucosal (protruding into the uterine cavity), intramural (within the muscle wall), and subserosal (extending toward the outer surface). Leiomyomas are estrogen-dependent and can cause symptoms including heavy menstrual bleeding, pelvic pressure, urinary frequency, and reproductive dysfunction. Treatment options range from observation to medical management with hormonal therapies, to surgical interventions such as myomectomy or hysterectomy depending on symptoms, size, location, and patient preferences.
Usage
Usage note: Specify location (submucosal, intramural, subserosal) when known; distinguish from malignant leiomyosarcoma.
