Abstract

Cystic dysplasia of the rete testis (CDT) is a very rare congenital benign testicular tumor that is often associated with ipsilateral genitourinary anomalies. It is usually found in the pediatric population and must be differentially diagnosed from a malignant lesion. Here we report the case of a 63-year-old man with a left inguinal hernia who visited our urologic outpatient clinic. Scrotal ultrasonography showed a left direct inguinal hernia in the inguinal area and a well-circumscribed cystic lesion containing multiple minute cysts with echogenic foci occupying almost one-third of the left testicular parenchyma. Testicular tumor markers were within the normal range and a computed tomography scan of the abdomen showed no genitourinary abnormalities. We presumed that the left testicular lesion was malignant, and the patient underwent radical orchiectomy. However, the pathologic examination revealed a CDT. Here we present this case of a 63-year-old man with an inguinal hernia accompanied by multiple cystic lesions on the left testis.
