Iatrogenic endometriosis and leiomyoma are rare complication of laparoscopic subtotal hysterectomy. I experienced a case of pelvic endometriosis and leiomyoma concurrently arising after laparoscopic subtotal hysterectomy 2 years ago. The patient was a 43-year-old woman, and her chief complaint was palpable mass with pelvic pain in pelvis. Contrast-enhanced computed tomography image showed multiple well enhanced masses. She underwent laparoscopic surgery which revealed pelvic endometriosis and leiomyomas. The solid masses in cul-de-sac and on the surface of rectum were revealed endometriosis. The solid masses on the surface of anterior abdominal wall and descending colon were revealed leiomyoma. Implantation of viable endometrial and leiomyoma tissues could occur during uterine morcellation at time of laparoscopic subtotal hysterectomy in some patients. Vigorous irrigation and meticulous inspection should be performed.
