ABSTRACT

Introduction: Parasitic leiomyoma is a rare condition that may be spontaneous or iatrogenic in origin. Laparoscopic uterine surgery and tissue morcellation are procedures that may lead to the development of parasitic leiomyoma.

Case Description: We report the case of a 36-year-old woman with a history of a laparoscopic myomectomy and uncontained power morcellation who presented to our institution 6 years later with 2 large parasitic fibroids together weighing over 1 kg. We additionally present a review of the literature on development of parasitic leiomyoma after myomectomy, summarizing 35 published cases in addition to our own.

Conclusion: Parasitic leiomyoma is estimated to occur after 0.20 to 1.25% of laparoscopic myomectomies, and is diverse in it’s presenting symptoms and surgical findings. Tissue morcellation is suspected to be a risk factor in the development of this condition.

Key Words: Parasitic leiomyomas, Myomectomy, Uncontained morcellation.
