The detection of anogenital lesions on a child is often accompanied by an implicit or explicit concern about the possibility of sexual abuse. Dermatologists have limited formal training in this area, and many clinicians have a high level of discomfort when a suspicion of child sexual abuse is raised. This may lead to over-or under-diagnosis, either of which will have a negative impact on the child and family. This monograph provides an overview of anogenital lesions on children with a focus on child sexual abuse and its correlates, including: normal developmental anatomy of the anogenital area; details of the initial evaluation for suspected sexual abuse; and a differential diagnosis of lesions that can mimic sexual trauma.
