Bilateral cystic dysplasia of the rete testis with renal adysplasia

Benign and Malignant Neoplasms of the Testis and Paratesticular Tissue

Benign and malignant tumors of the testes and paratesticular tissues present an interesting spectrum of diagnostic entities often encountered in routine surgical pathology practice. Germ cell tumors are the most common tumors of the testes and, despite a rising incidence, have excellent prognosis because of their radiosensitivity and/or effective chemotherapeutic agents. The proper classification of these tumors aids in the choice of appropriate treatment options. This article reviews benign and malignant neoplastic entities of the testes and paratesticular tissues and illustrates the classic pathologic characteristics. The differential diagnosis, along with ancillary studies, clinical significance, and presentation are discussed also.

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.
