A case of cystic fibrosis presenting as a right lower quadrant mass in a five-year-old white female is presented. At laparotomy, a mucoid, impacted appendix was found which microscopically suggested the diagnosis of cystic fibrosis. Cystic fibrosis must be added to conditions presenting with abdominal masses.
