AbstractAppendicitis is a common clinical problem but is not specific to a parasite. A ۴۳-year-old patient consulted for digestive troubles, mostly acute abdominal pain, in the right part. Taenia saginata was found in appendectomy. Different parasites were found in the histopathological evaluation of the appendix, mostly Enterobius vermicularis, but also Ascaris, Taenia, amoeba, and Schistosoma. Acute appendicitis was proven by submucosal fibrosis, active suppurative inflammation, and active granulomas surrounding eggs or larvae of parasites. However, parasites were detected by chance in uninflamed and histologically normal appendices or appendices with chronic inflammation removed during other surgical procedures. The role of parasites in the pathogenesis of acute appendicitis is unclear. An adapted antiparasitic treatment is always necessary after appendectomy following finding parasites.Keywords: Appendicitis, Enterobius vermicularis, Ascaris, Trichuris trichiura, Taenia–Schistosoma–Entamoeba histolytica
