title: Appendicitis by Enterobius vermicularis presenting with recurrent abdominal pain and eosinophilia A case report.
abstract: BACKGROUND
  Enterobius vermicularis (EV) is the most common parasitic infection in developed countries. Enterobius vermicularis infestation of the appendix can cause symptoms of appendiceal pain, independent of microscopic evidence of acute inflammation. The diagnosis of a parasitic infestation is generally achieved only after the pathologic examination of the resected appendices.
  
  
  METHODS
  We present a case of a 23 year old female with enterobiasis of appendix presented with clinical features of acute appendicitis. The appendix was surgically removed and the specimen was pathologically.
  
  
  CONCLUSIONS
  We highlight that the symptoms of appendicitis can be due to Enterobius vermicularis infestation also without any histological evidence of acute inflammation. High index of suspicion and including parasitic origin in differential diagnosis of abdominal disturbances might hopefully
