Abstract

Enterobius vermicularis (pin worm) is rarely found outside the gastro-intestinal tract. We describe a case of extra-intestinal pinworm in a child presented with intestinal obstruction and Meckel′s diverticulum were diagnosed. Resection and anastomosis was performed. Histopathological examination of one of mesenteric lymph nodes revealed ectopic Entrobius vermicularis worm surrounded by graulomatous reaction .Based on pathological findings, it is likely that the pinworms obtained access via the lymphatic pathway

Key words: Enterobius vermicularis, Intestinal obstruction
