Expecting the Unexpected: Schistosomial Appendicitis in Nonendemic Area

Abstract Background  Schistosomiasis is a granulomatous disease prevalent in tropical and subtropical areas. Appendicitis secondary to schistosomiasis is a rarely encountered presentation, even in endemic areas. Most acute intestinal schistosomiasis presents with abdominal pain and bloody diarrhea. Other atypical clinical presentations include intestinal obstruction, peritonitis, and acute appendicitis. Case Description  We report a case of a 37-year-old male from the Philippines who presented with the clinical picture of acute appendicitis and was treated with laparoscopic appendectomy. Pathological study revealed calcified Schistosomia japonicum's egg in a background of acute inflammation. Conclusion  Worldwide increase in immigration and tourism resulted in an increased number of schistosomiasis in nonendemic areas. Considering this, we are faced with the uncommon etiology of acute appendicitis.
