Swyer syndrome also known as pure or complete gonadal dysgenesis is a very rare disorder of sex development wherein the individuals are phenotypically females with 46, XY genotype and preserved mullerian structures. These individuals characteristically have dysgenetic streak gonads which carry an increased risk of malignant transformation. Prophylactic gonadectomy is highly recommended as soon as a clinical diagnosis is established to diminish the chances of tumor development. We present a case of complete gonadal dysgenesis with bilateral small gonads with a dysgerminoma arising in a background of gonadoblastoma in one gonad and immature teratoma in the other. The present case, besides adding a rare case to the literature, highlights the importance of detailed pre-operative assessment of gonadal size and prompt prophylactic gonadectomy in cases with gonadal dysgenesis.

Study Objective: To evaluate the prevalence of germ cell tumors and the clinical monitoring practices for those who deferred prophylactic gonadectomy in a large North American cohort of individuals with Turner syndrome with Y-chromosome mosaicism (TS+Y).
Method: A query of the medical records at multiple North American children's hospitals was done using ICD codes related to Turner Syndrome. A retrospective chart review was conducted on those patients between ages 0 to 30 years with Y-mosaicism.

Turner syndrome is a chromosomal disorder affecting females characterized by the partial or complete absence of one X chromosome. The pathogenesis of Turner syndrome primarily arises from chromosomal nondisjunction during gametogenesis, leading to various genotypic presentations. The most common genotype is 45, XO, representing a monosomy of the X chromosome.

This study investigates gonadal histology in individuals with Turner syndrome assigned female at birth and Y-chromosome material (TS+Y) who underwent prophylactic gonadectomy. Despite case reports suggesting spontaneous menarche and pregnancies in TS+Y, this research reveals the absence of germ cells, indicating low fertility likelihood. Germ cell neoplasia in-situ was present in some patients, emphasizing a non-negligible risk of cancer precursor.
