Leiomyoma
Chapter: 18
A benign tumor of smooth muscle origin. Grossly, leiomyomas are firm, pale gray, well circumscribed whorled lesions that can be subserosal, submucosal or intramural in location. They are composed of bundles of benign smooth muscle fibers similar to the myometrium. They can be asymtomatic or may cause abnormal uterine bleeding and pain requiring hysterectomy. It is the most common tumor of the female genital tract.
