Acute abdomen: An uncommon presentation of a common intestinal nematode.

Rizvi G, Rawat V, Pandey HS, Kumar M - Trop Parasitol (2015 Jul-Dec)

Bottom Line: 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.

ABSTRACT
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.

Figure 1: Case 1 nterobius vermicularis (female worm) in the wall of jejunum. Three rounded structures are present beneath the mucosa in the center of the picture with T shaped reproductive system clearly visible (H and E, ×10)

Mentions: Microscopic examination of the sections from the perforated area showed intense mixed inflammatory infiltrate in the mucosa with an edematous submucosa containing round, walled, intact structures of E. vermicularis with a “T” shaped reproductive system [Figure 1]. The serosal surface was covered with exudative membrane comprising of serofibrinous material with numerous eosinophils, polymorphs and red blood cells along with numerous rounded structures of the parasite with chitinous wall. The patient died a few days postoperatively.
