Testicular maldescent may be cryptorchid with descent being arrested along its normal pathway resulting in an abdominal, inguinal or high scrotal testis, or it may stray from the normal descent to settle in an ectopic site outside the scrotum; such as the perineum, pubic region, dorsum of the penis, femoral region, anterior abdominal wall and the contralateral scrotum. Management is orchidopexy through an inguinal crease incision as the length of the spermatic cord is normal. We report a 26 year old man with a left perineal testis who underwent orchidopexy as the testicular volume was normal.


Key words: Ectopic testis, Perineal testis, Maldescended testis

Maldescent of the testis is the most common anomaly of the genitalia (1). In most of these, the descent is arrested along its normal pathway resulting in an abdominal, inguinal or high scrotal testis. Rarely a testis may stray from the normal descent to settle in an ectopic site outside the ipsilateral scrotum. Congenital fascial bands at the root of the scrotum could be the cause of migration of the testis to an ectopic site (2). Some locations of an ectopic testis are the pubic region, dorsal penile area, femoral triangle, anterior abdominal wall, the opposite hemiscrotum and the perineum (2-8). Like undescended testes, ectopic testes are prone to trauma and testicular torsion. This is also associated with inguinal hernia and infertility (2, 5). The functional prognosis is similar (9). Orchidopexy through an inguinal incision is the standard procedure as the cord structures are of normal length (2). If the testis is severely atrophic, orchidectomy is undertaken and orchidopexy performed on the contralateral normal testis which is the standard procedure for a solitary testis (11). We report a case of perineal ectopic testis in an adult at the Coast Province General Hospital, Mombasa, Kenya treated in May 2016.


Case Presentation

A 26-year-old man presented at the surgical clinic of Coast Province General Hospital, Mombasa, Kenya, with a left sided perineal swelling that had been present since childhood. There was no discomfort. The patient was aware of having only one testis on the right. He had been investigated for infertility with a seminogram showing azoospermia. Examination of the patient revealed a normal right testis, empty left scrotum and a left perineal mass that elicited pain on pressure. The patient had an ultrasound scan of the scrotum and perineum that confirmed the left perineal mass as a testis. This testis, attached to the perineal skin, was of normal size and had a spermatic cord of adequate length. Left orchidopexy was done through an inguinal crease incision, with the placement of the testis in a subdartos pouch. The operation details are depicted in Figure 1.

The occurrence of ectopic testes is rare, with the perineal location as in our case being the most common (2). Most diagnoses of ectopic testes are made in early childhood (2, 7, 9, 10) with older children and adult presentation being rare (3, 4, 12, 13,) as in our case. Ku (3) reported a perineal testis in a 36-year-old, while Ates (12) reported the same in a 21-year-old. In patients with an empty scrotum, clinical examination of the normal path of testicular descent and the areas of ectopic location, form the mainstay of diagnosis (1, 2, 5) as was the situation in our patient with the ultrasound examination only confirming this. Our patient was managed by orchidopexy through an inguinal crease incision as the spermatic cord was of normal length as similarly stated in the literature (2, 10). The testicular volume was normal despite the tendency to atrophy with increased age (10). The contralateral testis was of normal volume; nevertheless, the patient had infertility with azoospermia. This was a coincidental finding. An ectopic testis after puberty may be normal in size but markedly deficient in spermatogenic components (3).



In maldescent of the testis with an empty scrotum, an examination of the normal path of descent and probable sites of  ectopic  location  is  mandatory.

Orchidopexy is straight forward with a good outcome.
