During the operation, the surgeon observed that both ovaries, the broad ligament, and the pelvis contained various nodules of striking size. On sectioning, uterus and ovaries contained multiple nodules of elastic consistency; microscopically, all consisted of benign smooth muscle tissue.ConclusionLeiomyomatosis may exhibit concomitant parametrial, pelvic, and bilateral ovarian involvement.
