Abstract:
We introduce a male patient with bilateral chryptorchidism submitted to surgery; during the intervention, macroscopically round macules were seen in the outer surface of both testes. In the round macules histological study, groups of seminiferous tubules were observed, including stroma and Leydig's intestitial cells surrounded of tunica albuginea, isolated from the rest of testicular parenchymal tissue; the diagnosis "Ectopic testicular parenchyma tissue" was confirmed by histopathological study. Due to the seminiferous tubules are surrounded by the tunica albuginea, with no apparent connection to the rest of the testicular parenchyma, a long-term assessment is required, both during puberty as well as in adulthood; owing to that can mislead and make unnecessary laparotomies and orchiectomies in the future.
