title: Testicular Mass in Late Adolescence: Not Always Malignant.
abstract: We present a rare case of cystic dysplasia of the testes in an adolescent boy who presented with testicular pain and found to have a palpable intratesticular mass. Ultrasound revealed an avascular cystic dilation of the testicle. Usually, a palpable intratesticular mass is malignant unless proven otherwise. However, on computed tomography scan, he was found to have agenesis of the ipsilateral kidney and dilation of the ipsilateral seminal vesicle. These findings were consistent with a congenital abnormality, suggesting that the testicular finding was likely cystic dysplasia of the testes, with low malignant potential. Thus, the patient did not undergo radical orchiectomy.
