title: [Parasitic infection of the appendix and its possible relationship to acute appendicitis].
abstract: From 1,600 surgically removed appendices, 24 (1.5%) were found to have helminths. Enterobius vermicularis was observed in 23 of the 24 specimens (95.8%) and Taenia sp was detected in only 1 (4.2%) case. Sixteen patients (66.7%) were less than 10 year-old; 15 patients were male and 9 female. Pathologic analysis disclosed acute neutrophilic inflammation in 12 cases and lymphoid hyperplasia in 10 of the 24 appendices. Gangrenous appendicitis was diagnosed in 3 cases and peritonitis was found in 11 of the 24 infested appendices. Parasitic infection of the appendix is an uncommon cause of acute appendicitis in children and adolescents.
