title: [XY gonadal dysgenesis (Swyer syndrome) with gonadoblastoma].
abstract: This is a case report of 46 xy gonadal dysgenesis (Swyer-syndrome) with bilateral androgen producing gonadoblastoma in streak gonads in a 15-year-old patient. The presenting features were: hypergonadotrophic hypogonadism, male pseudohermaphroditism and virilisation. A hypoplastic uterus with normal looking Fallopian tubes and bilateral adnexal tumors were detected through laparoscopy. A laparotomy was performed and the streak gonads with bilateral gonadoblastoma were removed. This led to a normalisation of serum testosterone and serum beta-HCG levels and an amelioration of signs of virilisation. Uterus and fallopian tubes were conserved during the operation. A second look laparoscopy 6 months later showed no evidence of recurrent tumor. No mutation were found in the sex-determining gene (SRY) on DNA-screening using SSCP assay.
