Parasitic infection mimicking acute appendicitis in an adult male-A rare case

The most common helminthic infection occurring worldwide is considered to be Enterobius Vermicularis commonly known as pinworm or thread worm mainly in GIT. [1,2]. The incidence of Enterobius Vermicularis infection is predominantly seen in children which is around 4% to 28% and is rarely seen in adults [3,4]. The most common route of infection is through feco-oral route. Enterobius Vermicularis infection is generally asymptomatic, if it infects appendix it may mimic acute appendicitis without histological evidence of acute inflammation [5,6].The pathological diagnosis of Enterobius Vermicularis in appendix is an infrequent finding and is mainly associated with chronic inflammatory infiltrate & eosinophils in the mucosa without invasion of mucosa by the parasite[7]. We report a case of 22 year old young adult male with right iliac fossa tenderness who underwent appendicectomy and pathology revealed Enterobius Vermicularis.
