Cystic dysplasia of the rete testis.

Cystic dysplasia of the rete testis (CDT) represents a diagnostically challenging condition in the pediatric population. We report a new case of CDT that differs in presentation from the majority of other cases in the literature in that the child complained of scrotal pain and had a solid mass on ultrasound. Based on this experience and a review of the literature, we recommend including CDT in the differential for all pediatric scrotal masses regardless of whether the mass is painless or painful, cystic or solid. As CDT is a benign lesion, we propose an individualized treatment of CDT.
