Presence of Enterobius vermicularis in surgical pieces of appendectomies Background: The frequency of appendicular presence of Enterobius vermicularis varies from 0.2 to 41.8%. It is generally a pathological fi nding. The luminal obstruction by the parasite may unveil an acute appendicitis. Aim: To study the frequency of Enterobius vermicularis presence in surgical pieces of appen-dectomies. Material and Methods: Analysis of surgical pieces of appendectomies processed at the pathology laboratory of a general hospital, between 1993 and 2010. Results: In 21.038 surgical pieces, the presence of Enterobius vermicularis was found in 322 (1.5%). Fifty nine percent were women and 71% were younger than 18 years. Acute infl ammation was confi rmed in 71%. A history of previous abdominal pain was present in 40 and 70% of patients with and without acute infl ammation in the surgical piece. Conclusions: In this series, the frequency of Enterobius vermicularis presence in surgical pieces of appendectomy was 1.5%.
