RESUMO
Ectopic localization of oxyuriasis is rare and frequently does not cause clinical problems. It has been reported in the vagina, endometrium, fallopian tube, peritoneal surface and ovary; In these localizations it often causes pseudo-tumoral granulomas. The aim of our study was to describe etiopathogenic and clinical criteria of this rare pathology. We report one case of endometrial enterobiasis which developed in a 28-year-old women and two cases of tubo-ovarian pseudotumoral abscesses containing the ova of enterobius which appeared as a latero-uterin mass in women aged 28 and 38 years. Enterobius vermicularis may cause tubo-ovarian abscess formation with necrotizing epitheloid granulomas mimicking tumors. Antihelminth therapies are successful.
