Uterine leiomyomas (fibroids) are very common benign tumors arising from the muscle of the uterus. This is a photograph of a hysterectomy specimen exhibiting multiple, large leiomyomas. Large leiomyomas often cause discomfort by compressing neighboring pelvic organs such as the bladder or colon. Myomectomy (removal of only the leiomyoma without removal of the uterus) is often the procedure of choice when child-bearing potential is to be maintained. Hysterectomy is assocated with less surgical morbidity than myomectomy in many published series and is the procedure of choice in treating symptomatic leimyomas when future pregnancy is not desired.
