Oxyuriasis in acute appendicitis. Description of two cases and review of the literature

Tozzi D., Delmonaco S., Pietroletti R., Leardi S.


Two cases of oxyuriasis of the appendix observed out of 870 cases of acute appendicitis are presented. Our aim was to examine the incidence of such condition and to correlate personal experience with data from the current literature. In personal experience, the incidence of pinworm appendicitis is low (0.22%) in line with a generalized decrease of oxyuriasis infestation. Such data is even more significant if we take into account that it is observed in a rural area. Of course we can confirm the presence, although rarely, of the pin-worm in the appendix but whether or not the parasite is cause of a true acute appendicitis is still matter of debate. Symptoms of our patients and signs on physical examination were those of typical acute appendicitis. Finally, treatment of such cases could not be represented merely by appendectomy, but antihelminthic therapy should be instituted in order to eradicate the parasite from the intestine of the patient as well as from parents since reinfection is frequent.
