Mild cystic fibrosis presenting as an asymptomatic distended appendiceal mass: A case report.

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.
