[Differential diagnosis of child sexual abuse]

The evaluation of a child presenting with an anogenital complaint or lesion can be challenging for both the clinician and the patient. The doctor met the real possibility that a diagnosis of a condition caused by sexual abuse will affect significantly the child and the family. A misdiagnosis of abuse or failure to recognize a treatable condition can also have detrimental consequences.
