Torsed reactive nodular fibrous pseudotumor in an adolescent: case report and review of the literature

We describe a case of a 13-year-old girl presenting with acute abdominal pain and imaging suggesting acute appendicitis. Upon laparoscopy, she was found to have a mass attached to the jejunum that had torsed upon its blood supply. On histopathologic studies, the mass was determined to be a reactive nodular fibrous pseudotumor. This lesion is a benign neoplasm that may arise from the gastrointestinal tract and has only been recently described in the literature. Our case is unique because it is the first report of reactive nodular fibrous pseudotumor presenting as a torsed polypoid lesion and the first arising in an adolescent.
