Acute appendicitis by Enterobius vermicularisan unusual etiology in children. The Enterobius vermicularis EV is one of the most common gastrointestinal helminth infections in children. Acute appendicitis AA is the most prevalent surgical emergency in niis.

The role of worms in the development of histologically confirmed AA is controversial, although the obstruction of the appendicular lumen could act as an exceptional trigger. A 7-year-old boy went to emergency department with severe abdominal pain of 20 hours, located in the right iliac fossa. On examination, the child had general status affectation.

Abdominal palpation aimed to voluntary defense in FID.

Blumberg and psoas signs were positive. Laboratory tests showed leukocytosis with neutrophilia and eosinophilia. Ultrasound visualized retrocaecal appendix of 6 mm. Urgent laparotomy appendectomy was performed, appreciating macroscopic inflammation of the appendix, without free liquid. Histopathological examination confirmed the diagnosis of appendicitis; cells of acute inflammation were invading the wall Fig. Given these findings, we contacted the family to start treatment apednicitis mebendazole.

The AA is the most common surgical cause of abdominal pain in children. It may be triggered by obstruction, decreased blood flow, mucosal ischemic injury or bacterial infection. Parasitic infections represent a minimum percentage of causes 2,3. The fecaliths are the most common trigger, nlos some parasites may be involved in its formation 4.

The presence of EV in the context of an AA ranges from 0. Helminthic invasion originates appendicular cramps caused by intermittent luminal obstruction, simulating a picture of AA 6.

Courses of perianal itching, bruxism and insomnia may also be present. The histopathological study shows infiltration of the appendicular wall by neutrophils and eosinophils, with granulomas and necrosis.

In exceptional cases, obstruction of nnios appendicular lumen by EV causes appendicitis confirmed histologically with acute inflammation 7.

The diagnosis of appendicitis is clinical. Laboratory tests, radiography and abdominal ultrasound are additional tests, but not diagnostic. In the context of a clinical appendicitis, the presence of previous appendicular colic and eosinophilia should make us to consider the existence of concomitant parasitic infection.

Moreover, In the presence of perianal pruritus, bruxism and insomnia we must suspect the appendicular colonization by EV 8,9. Face with a clinical diagnosis of AA, emergency appendectomy is indicated.

Laparoscopic appendectomy is associated with an increased risk of intraperitoneal settlement in the case of gastrointestinal helminthic infection 9.

Laparotomy appendectomy is considered a safer technique. The systematic review of the histopathological examination of the appendices has demonstrated the incidental presence of parasites, being EV the most prevalent in children Their discovery allows starting the treatment of the patient and family with mebendazole to eradicate the parasitic infection.

In conclusion, the systematic review and histological study of the appendages is essential. The incidental finding of intestinal parasitism by EV permits to start anthelminthic treatment.
