We report an unusual case of appendicitis in a 9-year-old girl in whom the wall of the appendix contained necrotizing granulomas, as well as eggs of Enterobius vermicularis. Although luminal E vermicularis adult parasites are commonly identified in the appendix and luminal eggs are occasionally seen, intramural worms and eggs are rare. We are unaware of earlier reports of ectopic intramural eggs in the appendix. It is important to and make a correct diagnosis, as both, the patient, as well as the family should be treated for enterobiasis.
