Taenia saginata is a zoonotic cestode causing taeniasis. Taeniasis refers to the intestinal infection with the adult stage of this tapeworm. An association between teaniasis and acute appendicitis is uncommon. We present the case of a 37 year old male who presented with abdominal pain for one day. He was diagnosed with having appendicitis and an appendectomy was performed. Pathology of the appendix showed Taenia saginata with eggs in the lumen. Histological analysis showed acute inflammation consistent with acute appendicitis caused by T. saginata.

Parasites are rarely associated with inflammation of the appendix. Generally, parasites cause acute abdominal pain via blocking the gut lumen. In this article, we presented a case of appendicitis where Enterobius vermicularis was detected in the surgical specimen and Taenia was detected in the stool. A 31 year old male patient was admitted to the emergency room with severe abdominal pain, which has begun two days ago. On physical examination, tenderness was positive on palpation of the right lower abdominal quadrant and the patient was operated on with the diagnosis of acute appendicitis. Histopathological examination of the patient's appendectomy material revealed numerous parts of parasites resembling Enterobius vermicularis and slight mucosal erosion. On parasitological examination of the patient's stool, Taenia eggs and adult forms were determined. Antiparasitic therapy was started with niclosamide for taeniasis and albendazole for enterobiasis. Parasitic infections can mimic acute appendicitis clinically. Radiological and laboratory findings do not help to distinguish the diagnosis of acute appendicitis. In the histopathological examination of the appendix, the findings of acute inflammation of the appendix wall may not be defined. For patients with normal histopathological examination, screening for parasites should be done, and anti-parasitic treatment should be started after appendectomy.

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.
