Infestation with Enterobius (Oxyuris) vermicularis is very common but seldom produces lesions and even more rarely causes granulomas. Two cases of oxyuris granulomas/nodules), one in the serosa of ovaries and left fallopian tube in a female of 32-years and the other in the submucosa of the appendix in a 10-year old girl are identified by the presence of true necrotizing granulomas containing the parasite. The pathogenesis and differential diagnosis of abdominal granulomas is discussed.
