The most common benign gyn tumor of the myometrium is which?

• A. Leiomyoma
• B. Endometrial polyp
• C. Adenomyosis
• D. Fibroadenoma

Answer: (A)

The myometrium can develop benign tumors from smooth muscle cells, and the most common of these is a leiomyoma, commonly called a fibroid. Leiomyomas are benign, hormone-responsive tumors that often arise within the muscular wall of the uterus and may be multiple. They tend to enlarge with estrogen exposure (during reproductive years) and shrink after menopause. Endometrial polyps come from the lining of the uterus (endometrium), not the myometrium. Adenomyosis involves endometrial tissue invading into the myometrium, causing diffuse thickening rather than a discrete tumor. Fibroadenoma is a breast lesion, not a uterine tumor.
