title: A case of 46, XY DSD presenting as a crossed ectopic gonad with a contralateral sliding inguinal hernia.
abstract: A three-month-old boy was referred to our facility for the treatment of a right impalpable testis, left inguinal hernia, and penoscrotal hypospadias with asymmetric external genitalia. The left gonad was palpated in the left scrotum. The chromosomal study revealed a normal male 46, XY karyotype. Operative findings showed that the right streak gonad, uterus, and fallopian tubes were in the wall of the left hernia sac, forming a sliding hernia. Laparoscopy confirmed that the right gonadal vessels had crossed to the left internal inguinal ring. Herniorrhaphy was done and the right streak gonad, uterus, and fallopian tubes were excised. An exploration of the left gonad revealed an ovotestis. The ovary was removed, and a left testicular biopsy was simultaneously performed. A one-stage hypospadias repair using Koyanagi procedure was also performed. The pathological findings showed an ovarian stroma in the right gonad and left ovary. Only Sertoli cells were detected in the biopsied specimen from the left testis.
