The general review article by Symmers1 leaves little to be added to the description of the pathology of extraintestinal granulomas due to Enterobius vermicularis. The purpose of the present report is simply to describe a case of Enterobius granuloma in the pelvic peritoneum of a 16-month-old white girl, apparently the youngest patient so far reported in whom such lesion has been found.
Symmers reviewed the world literature and found 16 cases of pelvic peritoneal lesions containing Enterobius or its ova, and he added two such cases of his own as well as a third case of a granuloma in a ureter. Only 2 of these 18 peritoneal granulomas were of clinical significance, the remainder being incidental necropsy or surgical findings.
Since publication of Symmers article, there have been other case reports of granulomas due to Enterobius in the female genital tract and the abdominal cavity.*
