Co-infection with Enterobius vermicularis and Taenia saginata mimicking acute appendicitis

In this report, we describe an unusual case of verminous appendicitis due to Enterobius vermicularis and Taenia saginata in a 29-year-old woman from Iran. The histopathological examinations and parasitological descriptions of both worms found in the appendix lumen are discussed. The removed appendix exhibited the macroscopic and microscopic features of acute appendicitis. Antihelminthic therapy was initiated with single doses of praziquantel for the taeniasis and mebendazole for the enterobiasis, and the patient was discharged.
