Testicular Vanishing Syndrome – A Rare Clinical Entity

Vanishing Testes Syndrome (VTS) also known as Testicular Regression Syndrome (TRS) is a condition in which there is absence or incomplete development of testis of varying degrees in 46XY subjects with normal external genitalia. This situation is observed in overall 5% of patients presented with cryptorchidism. We relate a case of VTS in an adult here, in which the subject had absent left testes on clinical examination, but MRI showed presence of atrophic testes at the level of deep inguinal ring. Orchidectomy of left testis was performed and the left testicular artery was followed which had a blind ending. The blind end was also resected and both of the specimens of the parenchyma of testicular tissues and blood vessel were sent for biopsy.
