Rare case of an anorectal leiomyoma

Abstract

Introduction Leiomyoma is a kind of benign tumors of smooth muscle origin, occurring mostly throughout the genitourinary system. They are rarely found in the anorectal region, where they represent less than 0.1% of the tumors of the rectum. Due to this exceptional occurrence, we report a case of leiomyoma arising in the anorectal region.

Case outline A 43-year-old otherwise healthy woman presents with the big mass in analorectal region. Major complain is pain and discomfort while sitting. Magnetic resonance imaging is done and pathohistology report confirmed large leiomyoma. Abdominoperianeal resection of the rectum was performed due to the size of the tumor. Postoperative course was uneventful.

Conclusion There is no gold standard technique, and decision about the best surgical approach for all pathohistological types of tumors in the anorectal region. The decision sometimes has to be made according to size and major complains.
