Enterobius Vermicularis Infestation of the Uterine Cavity: A Rare Cause of Dysfunctional Uterine Bleeding

Extraintestinal infestations of Enterobius are extremely rare, and the worm larvae may migrate primarily to invade the female genital tract. A 47 year-old woman having irregular menstruation for six months was admitted and had endometrial biopsy. The patient, whose pathology report had enterobiasis in the endometrium, was cured by treatment with 500 mg mebendazole. Endometrial sampling should be considered by the clinician before unnecessary and aggressive surgery in patients presenting with a similar complaint.
