What is Enterobius vermicularis (pinworm)?
Summary of Enterobius vermicularis (Pinworm) The pinworm (Enterobius vermicularis) is a parasitic nematode (roundworm) and a common intestinal parasite, transmitted by the fecal-oral route, whose primary symptom is itching in the anal area. Diagnosis is via visualization of eggs with the “scotch tape test.” Treatment is with bendazoles.

Adult males of Enterobius vermicularis measure up to 2.5 mm long by 0.1—0.2 mm wide; adult females measure 8—13 mm long by 0.3-0.5 mm wide. Adult males have a blunt posterior end with a single spicule; females possess a long pointed tail.
Is Enterobius vermicularis associated with acute appendicitis?
Enterobius vermicularisis one of the commonest parasitic infestations worldwide but its association with acute appendicitis remains controversial. It is very rarely encountered during appendectomy. The aim of this paper is to report a case of acute appendicitis caused by Enterobius vermicularis.
How is Enterobius vermicularis expelled from its host?
It is an agent that blocks neuromuscular depolarization making the worm undergo spastic paralysis through continuous nicotinic activation, ultimately the worm detaches from the host and consequently will be expelled through defecation [13]. Table 1reviews the most important reports regarding acute appendicitis and Enterobius vermicularis.
