Complicated acute appendicitis? An unusual differential.

Acute appendicitis is a common surgical diagnosis but several differential diagnoses exist and should be considered. Internal concealment is one such diagnosis. We present a case of a young man taken to the operating room with a preoperative diagnosis of complicated acute appendicitis. A ruptured caecum was encountered and several free-floating drug pellets were present. Attending doctors should consider this differential in the high prevalence areas and, whenever encountered, they should strongly consider early reporting.
