Abstract:

Laparoscopy Trocar port site leiomyoma after laparoscopic myomectomy is very rare. Its pathogenesis may be related to iatrogenic implantation after pelvic surgery. This article reports a case of abdominal wall leiomyoma treated in the gynecology minimally invasive center of Beijing Obstetrics and Gynecology Hospital of Capital Medical University. The patient underwent laparoscopic myomectomy in our hospital at 2010. Six years ago, the patient felt a mass at the previous surgical scar on the left lower abdomen at 2015 and the mass that had been progressively increasing over a 3-year period since 2018. Laparotomy was performed on admission at 2021. During the operation, a 4.0 cm×4.0 cm leiomyoma nodule was found in the fat layer of the abdominal wall of the previous left laparoscopy Trocar port site. The abdominal wall leiomyoma was confirmed by histopathology and immunohistochemistry. The formation of leiomyoma in the abdominal wall of laparoscopy Trocar port site was considered to be iatrogenic parasitism caused by previous laparoscopic myomectomy. The prevention of iatrogenic parasitic leiomyoma is very important, but it cannot completely avoid the formation of iatrogenic parasitic leiomyoma, which needs further research.
