ABSTRACT
Genital tract bleeding in prepubertal girls is a rare clinical condition, which can occur for multiple reasons. It frequently generates anxiety in the family and in health care professionals. A thorough anamnesis and careful genital inspection can give important diagnostic hints; however, there are cases in which the cause remains doubtful and a complete gynecological evaluation (including cultures and vaginoscopy) is necessary. Therefore, the attending physician should always consider less frequent diagnoses in order to perform the necessary studies in a sequential and rational manner. We present the case of a preschool girl with vaginal bleeding due to pinworm endometritis, which, to our knowledge, has never been reported before as a cause of genital bleeding in prepubertal girls.
