Extra-Uterine Leiomyoma Presenting After Hysterectomy

Leiomyomas are a common gynaecological finding affecting 20-30% of women over the age of 35, with prevalence decreasing following menopause. Around 25% of women present clinically with a leiomyoma, which are most commonly found within the uterus. Rarer extra-uterine locations include the broad ligament, cervix, and vagina. We present a rare case of an extra-uterine leiomyoma located in the perineum of a 59-year-old female. Our case highlights the importance for extra-uterine leiomyoma to be considered as a differential diagnosis in patients presenting with a pelvic mass following hysterectomy.
