Abstract
Background: Appendiceal parasites can cause symptoms of appendicitis. Although the symptomatology imitates acute appendicitis clinically, the true nature of disease is diagnosed through histological examination. The aim of this study is to therefore determine the prevalence of E. Vermicularis in appendicectomy specimens to relate this to acute inflammation histologically.Materials & Methods: Histological data on all appendectomy specimens with a clinical diagnosis of acute appendicitis were retrieved from the archives of department of pathology, B.P.K.I.H.S, over the period of five years (January 2004- December 2008) and was analyzed retrospectively.Results: There were a total of 1528 patients. M:F ratio being 1.2:1.Inflamed appendix constituted for 94.24% of all cases. There were a total of six (0.39%) appendicectomy specimens which showed presence of oxyuriasis appendix. Though all patients with oxyuriasis presented with appendicial colic only one (1) out of the six cases of oxyuriasis showed histologic evidence of inflammation. Conclusion: We conclude that enterobius does not frequently cause inflammation of appendix though it may clinically mimic acute appendicitis. Since it represents a disease curable without necessitating surgery, symptomatology awareness is stressed upon.Journal of Pathology of Nepal (2015) Vol. 5, 720-722
Highlights
Appendicitis is the most common surgical cause of acute abdominal pain, affecting 7% of humans during their lifetimes.[1]
The negative appendicectomy rate reported in the literature varies; typical figures are between 7% and 20% in men and 20% and 45% in women.[4]

Summary
Appendicitis is the most common surgical cause of acute abdominal pain, affecting 7% of humans during their lifetimes.[1]. Correspondence: the negative appendicectomy rate reported in the literature varies; typical figures are between 7% and 20% in men and 20% and 45% in women.[4] These are high figures for a common disease at the threshold of the 21st century and they persist despite many attempts to refine the preoperative diagnosis. Enterobius Vermicularis infestation in appendices largely unchanged over the last 70 years.[5] One such cause of negative appendicectomy could be infestation of the appendix by Enterobius vermicularis, commonly known as pinworm or threadworm, responsible for a widespread parasite infection estimation to affect up to 209 million people worldwide.[6] The possible role of the parasite in causing acute appendicitis has been a matter of great dispute and has been discussed for almost more than 100 years.[7].
