title: Appendicitis with perforation: a reminder to internists.
abstract: Over a two-year period, four adults with appendicitis were admitted to the medical service with manifestations sufficiently atypical to obscure the correct diagnosis. Perforation of the appendix was found in each, and abscess formation occurred in two cases. One patient died. The experience with these cases reemphasizes the protean manifestations of complicated appendicitis.
