Enterobius vermicularis is a common parasitic infection of the intestine which is rarely symptomatic. It is unusual to find it in the wall or outside the gastrointestinal tract. We encountered five such cases where we observed the worm outside the lumen of the intestine. The pathological findings and the clinical features are discussed. This case series highlight that E. vermicularis can be the cause of pathology within the abdomen and should be considered in the differential diagnosis of some commonly encountered abdominal conditions.
