Pinworm in the Appendix: An Unusual Cause of Appendiceal Inflammation; A Case Report

Purpose Enterobius Vermicularis , usually causing perianal pruritus in children, can rarely become the cause of acute appendicitis. It is imperative to discuss this unique manifestation of this parasitic infestation. Methods The Medline database was extensively searched for literature covering the different aspects of this clinical manifestation to discuss alongside the unusual case presentation. Results Enterobius Vermicularis is a nematode endemic to various parts of the developing world with a significantly rising prevalence. Colonizing humans as a primary host, the parasite usually causes perianal pruritus. In rare instances, however, after successful migration and obstruction of the appendiceal lumen, acute appendicitis may ensue. Acute appendicitis, diagnosed via clinical presentation and radiologic investigation, warrants surgical intervention. Conclusion Parasitic manifestation may be visible perioperatively or become evident upon histopathology. Anti-helminthic therapy commencement should not be delayed to effectively reduce transmission risk and inevitably cure the condition.
