Leiomyoma is a benign smooth muscle tumor that can occur in any organ but is most commonly found in the uterus, where it is often referred to as a uterine fibroid. Leiomyomas are the most common benign tumors in women and are typically discovered during the reproductive years.
Pathophysiology[edit | edit source]
Leiomyomas are composed of smooth muscle cells and fibrous connective tissue. They arise from the smooth muscle layer of the uterus, known as the myometrium, but can also occur in other locations such as the esophagus, small intestine, and skin. The exact cause of leiomyoma development is not fully understood, but it is believed to be related to hormonal factors, particularly estrogen and progesterone.
Clinical Presentation[edit | edit source]
Many leiomyomas are asymptomatic and are discovered incidentally during pelvic examinations or imaging studies. When symptoms do occur, they may include:
- Abnormal uterine bleeding
- Pelvic pain or pressure
- Frequent urination
- Constipation
- Infertility
Diagnosis[edit | edit source]
The diagnosis of leiomyoma is typically made through imaging studies such as ultrasound or magnetic resonance imaging (MRI). Histological examination of tissue samples can confirm the diagnosis.
Treatment[edit | edit source]
Treatment options for leiomyoma depend on the size, location, and symptoms. They include:
- Observation for asymptomatic cases
- Medications such as gonadotropin-releasing hormone (GnRH) agonists to shrink the tumors
- Surgical options like myomectomy or hysterectomy
- Minimally invasive procedures such as uterine artery embolization
Prognosis[edit | edit source]
Leiomyomas are benign and do not metastasize. However, they can cause significant symptoms and complications, such as anemia from heavy bleeding. Rarely, a leiomyoma may undergo malignant transformation into a leiomyosarcoma.
