Solitary rectal ulcer syndrome (SRUS) is a rare, benign disorder in children that usually presents with rectal bleeding, constipation, mucous discharge, prolonged straining, tenesmus, lower abdominal pain, and localized pain in the perineal area. The underlying etiology is not well understood, but it is secondary to ischemic changes and trauma in the rectum associated with paradoxical contraction of the pelvic floor and the external anal sphincter muscles; rectal prolapse has also been implicated in the pathogenesis. This syndrome is diagnosed based on clinical symptoms and endoscopic and histological findings, but SRUS often goes unrecognized or is easily confused with other diseases such as inflammatory bowel disease, amoebiasis, malignancy, and other causes of rectal bleeding such as a juvenile polyps.
