Genitourinary manifestations of hereditary cancer predisposition syndromes in children.

Several hereditary cancer predisposition syndromes are associated with genitourinary (GU) manifestations in children. The GU manifestation may be the first symptom of a more global syndrome to arise, which places the pediatric urologist in a unique position to impact the health of the child. Some GU manifestations are pathognomonic for a particular hereditary cancer predisposition syndrome, which can prompt genetic testing and enhanced surveillance for other features of the condition. In other cases, knowledge of an underlying hereditary cancer predisposition syndrome alters treatment decisions. This review focuses on hereditary cancer predisposition syndromes that impact the GU tract and are likely to be seen by a pediatric urologist.
