In Perineal ectopic testis (PET), the testis is located between the penoscrotal raphe and genitofemoral fold. PET incidence is <%1 of all undescended testes.The first case was reported by John Hunter in 1786. It is a rare congenital anomaly. It can be diagnosed with physical examination and ultrasound. An empty hemiscrotum gives rise to suspicion of the disorder of undescended testis. The testis progresses usually with the guidance of the gubernaculum and the ectopic occurs while the progression continues along a wrong gubernaculer pathway. This imperfection is associated with the fixation disorder of the gubernaculum testis and this leads to an abnormal position of the testis.
