Clinical and Histopathological Evaluations of Testicular Regression Syn-drome: A Case Report

Abstract

BackgroundTesticular regression syndrome (TRS) is defined as the partial or total absence of testicular tissue in 46XY patients with normal external genitalia. The incidence of TRS has been reported to be less than 5% in patients with cryptorchidism. Herein, we report a case of a one-year old boy who underwent surgical exploration with an initial diagnosis of cryptorchidism.Case descriptiona one-year old male came to the outpatient clinic at Al Emadi Hospital, Doha, Qatar. Physical examination revealed normal external genitalia with palpable right testis and non-palpable left testis. The initial diagnosis was cryptorchidism. Testicular structure was not identified and a presumed testicular remnant in the left superficial inguinal ring was sent for histological examination. The histological examination revealed a fibrovascular nodule, spermatic cord structures, calcification and hemosiderin deposits supporting the diagnosis of TRS.ConclusionWhen patient fulfills clinical and pathological criteria for TRS, we should consider the possibility of orchiopexy and testicular prosthesis implantation to decrease the risk of testicular torsion and negative psychological effects.
