Synopsis

Laxity of the anus and anal dilatation may be found with neurologic disorders and chronic constipation but may also be consistent with sexual abuse. Anal dilatation of any size is considered a normal reflex if stool is present in the rectal vault or if dilation occurs after the child has been in the prone knee-chest position for more than 30 seconds. However, anal dilatation of 20 mm or greater, without stool in the rectal vault, is suspicious for abuse.

Childhood sexual abuse is a problem of epidemic proportions affecting children of all ages and economic and cultural backgrounds. Although awareness of child abuse is increasing, it may be challenging to differentiate findings attributable to sexual abuse from those of other benign anogenital skin conditions.
