Abstract

Ectopic scrotum is a rare condition, which is described as an anomalous position of one hemiscrotum along the inguinal canal. This anomaly is associated with other genitourinary anomalies. We report a 5-year-old boy with ectopic scrotum and penile torsion, who was successfully treated by simultaneous surgery.

 Introduction



Ectopic scrotum is a rare condition, which is described as an anomalous position of one hemiscrotum along the inguinal canal. This anomaly is associated with other genitourinary anomalies.[1] We report our experience of surgical correction of ectopic scrotum with penile torsion.

 Case Report



A 3-year-old boy was referred to our center with genital abnormalities. He had surgical repairs of omphalocele, bilateral inguinal hernia, and right lower extremity abnormality. He received intramuscular injections of testosterone enanthate for the management of micropenis. On physical examination, the right hemiscrotum was located in the right infrainguinal region and contained the right testis. The left hemiscrotum was located in the normal position with the left retractile testis. He had 90° clockwise penile torsion [Figure 1]a. Renal and bladder ultrasonography showed right small kidney. On dimercaptosuccinic acid renal scan, the split function of the right kidney was 24%.{Figure 1}

At the age of 5 years, we performed surgical correction of ectopic scrotum and penile torsion [Figure 1]. Degloving was done following transscrotal orchiopexy for the left retractile testis. After that, 45° clockwise penile torsion persisted. Subsequently, a dartos flap was dissected from the dorsal skin. The flap was transposed ventrally from the left side of the penis and fixed to the tunica albuginea of the right corpus cavernosum. After penile torsion was improved, we performed rotation flap scrotoplasty with right orchiopexy. The ectopic scrotal skin was pedicled inferiorly with a superior pedicle to the intervening skin. The flaps were mobilized and switched, and the right testis was fixed in the right rotated hemiscrotum. Byars flap was crisscrossed for skin covering of the penis.

On follow-up evaluation at 16 months after the surgery, 15° clockwise penile torsion persisted. The rotated scrotum had an acceptable cosmetic appearance, and both testes were viable in the scrotum [Figure 2].{Figure 2}

 Discussion



Ectopic scrotum is extremely rare, with 27 cases reported in the literature up to 2017.[2] Two theories have been proposed to account for this condition: abnormalities in the development of the gubernaculum with its secondary attachment to the skin covering the genital tubercle and failure of fusion of the outer genital folds due to heel compression during intrauterine life.[3]

The location of ectopic scrotum can be suprainguinal, infrainguinal, or perineal, and suprainguinal type is the most common.[1] Ectopic scrotum is associated with inguinal hernias, penile torsion, hypospadias, patent urachus, imperforate anus, bladder exstrophy, cleft lip or palate, and leg deformities.[1],[2] In one review, 70% of boys with a suprainguinal ectopic scrotum had ipsilateral upper urinary tract anomalies, including renal agenesis, renal dysplasia, and ectopic ureter.[4] Our patient with infrainguinal ectopic scrotum had renal hypoplasia, omphalocele, penile torsion, inguinal hernia, and leg deformity.

The management of ectopic scrotum includes one-stage repair (simultaneous scrotoplasty and orchiopexy), two-stage repair (orchiopexy with subsequent scrotoplasty or scrotoplasty with subsequent orchiopexy), and excision of ectopic scrotal tissue.[2] We performed one-stage repair for infrainguinal ectopic scrotum with penoplasty for penile torsion without any postoperative complication.

In conclusion, simultaneous one-stage repair of ectopic scrotum and penoplasty of penile torsion could be performed safely. The rotated scrotum had a good cosmetic appearance, and the testes were viable in the scrotum.
