What is a Leiomyoma?

A leiomyoma (pronounced lie-o-my-O-ma) is a benign (non-cancerous) tumor that arises from smooth muscle tissue. Smooth muscle is found in the walls of organs and blood vessels throughout the body. Therefore, leiomyomas can develop in various locations. The most common type, and the one most people associate with the term, is the uterine fibroid.

Types of Leiomyomas

Leiomyomas can be categorized by their location:

Uterine Leiomyomas (Fibroids)

These are the most common type of leiomyoma. They develop in the uterus, often causing symptoms like heavy bleeding, pelvic pain, and pressure. Uterine fibroids are extremely common, affecting a significant percentage of women during their reproductive years.

Other Locations

Leiomyomas can also occur in other locations, including:

Gastrointestinal Tract: Leiomyomas in the stomach, small intestine, or colon are less common than uterine fibroids.
Skin: These are often called dermatofibromas and typically present as small, firm nodules.
Esophagus: Leiomyomas in the esophagus can cause difficulty swallowing.
Blood Vessels: These are rare and can sometimes be associated with certain genetic syndromes.

Causes of Leiomyomas

The exact cause of leiomyomas isn't fully understood. However, several factors are thought to play a role:

Genetics: Family history of fibroids increases the risk.
Hormones: Estrogen and progesterone, the female sex hormones, appear to stimulate the growth of leiomyomas. This explains why fibroids often grow during the reproductive years and shrink after menopause.
Race: African American women have a higher incidence of uterine fibroids.

Symptoms of Leiomyomas

Symptoms vary depending on the location and size of the leiomyoma. For uterine fibroids, common symptoms include:

Heavy menstrual bleeding (menorrhagia): This is often the most prominent symptom.
Prolonged menstrual periods (menometrorrhagia): Bleeding that lasts longer than usual.
Pelvic pain or pressure: This can range from mild discomfort to severe pain.
Frequent urination: Due to pressure on the bladder.
Constipation: Due to pressure on the intestines.
Infertility or recurrent miscarriage: In some cases, large fibroids can interfere with fertility.

Diagnosis of Leiomyomas

Diagnosis typically involves a combination of:

Pelvic exam: A physical examination to assess the size and location of the uterus.
Ultrasound: This imaging test provides detailed images of the uterus and helps identify fibroids.
MRI: Magnetic resonance imaging can provide even more detailed images, especially for complex cases.
Hysteroscopy: A procedure where a thin, lighted scope is inserted into the uterus to visualize the inside.

Treatment of Leiomyomas

Treatment options depend on the severity of symptoms, the size and location of the leiomyoma, and the patient's desire to have children. Options include:

Observation: For asymptomatic fibroids, watchful waiting may be an appropriate approach.
Medication: Medications like GnRH agonists can temporarily shrink fibroids, but they have side effects.
Myomectomy: Surgical removal of fibroids while preserving the uterus. This is a good option for women who want to preserve fertility.
Hysterectomy: Surgical removal of the uterus. This is typically considered for women who are finished having children or whose symptoms are severe and unresponsive to other treatments.
Uterine Fibroid Embolization (UFE): A minimally invasive procedure that blocks blood flow to the fibroids, causing them to shrink.
Magnetic Resonance-guided Focused Ultrasound Surgery (MRgFUS): A non-invasive procedure that uses focused ultrasound energy to destroy fibroids.

Living with Leiomyomas

Many women with leiomyomas live normal, healthy lives. However, it's crucial to seek medical attention if you experience concerning symptoms. Early diagnosis and appropriate management can significantly improve your quality of life. Regular check-ups with your gynecologist are essential for monitoring fibroids and addressing any related concerns.
