A complicated case of appendicitis

A case is presented of acute appendicitis in a 50-year-old man with unsuspected carcinoma of the right colon. This association is emphasised as acute appendicitis is an important marker of colonic carcinoma in the older age group. The value of doing routine barium enema examination in these patients after appendicectomy is discussed. Further unusual features of this carcinoma were radiographically visible calcification and spread into the right kidney.
