# A Case of Parasitic Leiomyoma After Laparoscopic Myomectomy With Power Morcellator

## TL;DR

A woman developed a parasitic leiomyoma years after a laparoscopic myomectomy using a power morcellator, highlighting a rare but important long-term complication.

## Contribution

This case highlights the long-term risk of parasitic leiomyoma following laparoscopic myomectomy with a power morcellator.

## Key findings

- A parasitic leiomyoma was diagnosed 12 years after laparoscopic myomectomy using a power morcellator.
- The tumor was located in the pouch of Douglas and was firmly adhered to surrounding tissues.
- The case underscores the need for long-term follow-up in patients who undergo laparoscopic myomectomy with power morcellators.

## Abstract

As the growth of morcellated leiomyoma fragments is slow, iatrogenic parasitic leiomyomas are recognized as late complications of laparoscopic myomectomies. We present a case of parasitic leiomyoma diagnosed several years following laparoscopic myomectomy using a power morcellator. A 48-year-old Japanese woman presented with a pelvic mass. At 36 years old, she underwent laparotomic myomectomy using a power morcellator for uterine leiomyomas. Twelve years after the initial laparoscopic myomectomy, multiple subserous leiomyomas were detected. She was treated by open surgery. A solid tumor was found in the pouch of Douglas, which was firmly adhered to surrounding tissues. It was diagnosed as a parasitic leiomyoma. Gynecologists should be aware of the risk of iatrogenic parasitic leiomyoma development as a late complication of laparoscopic myomectomy using a power morcellator. Moreover, patients should be followed up at least until menopause.
