Recurrent abdominal pain due to chronic appendiceal disease.

Recurrent appendicitis and chronic appendicitis are the subjects of much controversy, but long-standing inflammation of the appendix and surrounding tissues has been reported in rare instances. We have described two patients, both with recurrent episodes of abdominal pain, who subsequently were shown to have chronic appendiceal disease. Appendiceal disease should be considered in the differential diagnosis in patients with recurrent abdominal pain.
