INTRODUCTION:

Frasier Syndrome is an autosomal dominant inherited disease with a prevalence of less than 1 per million live births. To date, about 150 cases have been described. This syndrome is characterized by male pseudohermaphroditism, 46, XY gonadal dysgenesis, and glomerular disease, all caused by a mutation of the WT1 gene. It is essential to learn more about this disease, not only because of the high risk of ovarian neoplasia, but also because its early diagnosis will improve the prognosis.

CLINICAL CASES:

We report the case of a 16-year-old woman who consulted for primary amenorrhea and absence of secondary sexual characteristics. As medical history, she highlighted steroid-resistant focal segmental glomerulonephritis since childhood. The examination revealed Tanner stage 1. Complementary tests revealed the absence of the uterus and adnexa and hypergonadotropic hypogonadism with a 46, XY karyotype. Given the findings, it was decided to perform an exploratory laparoscopy and bilateral salpingo-oophorectomy. The anatomopathological result reported dysgerminoma of the right ovary. The clinical suspicion was confirmed by genetic study, which reported a mutation of the WT1 gene, diagnostic of Frasier Syndrome. Currently, the patient undergoes, along with immunosuppressive treatment, hormone replacement therapy, with a favorable evolution.

CONCLUSION:

Early diagnosis of Frasier Syndrome is essential given the associated risk of malignancy. The low frequency of the disease and the usual association of delayed puberty in patients with chronic diseases may lead to a diagnostic delay. Therefore, reporting the diagnosed cases of this syndrome, as well as its multidisciplinary management, is essential to improve knowledge about this rare disease.
