Trauma to the appendix. A report of two cases.

Only two cases of trauma to the vermiform appendix are recorded in the English literature. This report adds two more cases: one due to a penetrating bullet wound of the abdomen where tangential laceration of the appendix was the only intra-abdominal injury, the other an avulsion of the appendix from the mesoappendix resulting from blunt abdominal trauma. Preoperative diagnosis of this specific lesion could not be made. Both patients were successfully managed by appendectomy.
