Cystic dysplasia of the rete testis: A rare mimicker of malignancy in pediatric patients

Cystic dysplasia of the rete testis is a rare congenital condition, commonly affecting children, and often presents as a painless scrotal swelling or testicular mass resembling malignancy. Frequently linked with genitourinary anomalies like ipsilateral renal agenesis or dysplasia. We report 14-year-old boy with progressive left scrotal swelling since early childhood. Imaging studies revealed cystic loculations displacing the testicular parenchyma, with normal tumor markers. A left orchidectomy was performed due to extensive lesion and complete parenchymal displacement, with histopathology confirming CDT. This case highlights the role of advanced imaging in accurate diagnosis and the importance of a multidisciplinary approach in management.
