Enterobius vermicularis is a worldwide common parasite which live predominantly in the caecum and appendices, and entirely restricted to human. In our study, we intented to ezamine the age and sex of the patients and the number of these parasites which can be seen in the human appendectomy material. 36 (2%) E. vermicularis infected appendices among the 1842 appendectomy material which were examined in a 24 month period between January 2009 and January 2011 at Erzurum Regional Training and Research Hospital Pathology Laboratory were discussed. Twentyseven of 36 specimens showed no sing of acute inflammation. Its known that parasites at appendices usually stays without showing signs of inflammation, rarely acute appendicitis seems. At some materials many E. vermicularis were seen. According to our archive, appendectomy in men (59.5%) is applied more than women but E. vermicularis is more common in women (58.3%). Despite appendectomy is applied more frequently at 2nd and 3rd decades, E. vermicularis was seen frequently at 2nd and 3rd decades (58%). The average age of appendectomy patients was 26 and it was 23.4 at these patients.
