Leiomyoma is a benign soft tissue tumor of mesenchymal origin that derives from smooth muscle fibers [1, 2]. In the digestive tract, the anorectal location is uncommon and is usually diagnosed late due to intraluminal growth in over 50% of the cases [2]. We present the case of a 55-year-old woman who presented with a peri anal mass found more than 3 years ago. The 5cmx4cmx3cm mass was located in the left side of the anus, MRI revealed a clear demarcation between the mass and the external anal sphincter. Surgery was performed with a para-anal incision. The external anal sphincter was largely intact. A complete extracapsular dissection was performed.
