Injuries in the genital region of boys are mostly caused by accidents. In this study, three cases of child abuse and one case suspicious for child abuse but explainable by a congenital undiscovered malformation are presented. Injuries or findings in the genital region are especially suspicious for child abuse, including sexual abuse. Because of the possible misinterpretation and the consequences of a false confirmation of a child abuse, an interdisciplinary cooperation between pediatrics, forensic experts, and pediatric urologist should be carried out in doubtful cases.
