    Abstract:
    Gonadal dysgenesis patients with Y chromosomal material are subject to increased risk for germ cell tumors. We report a case of an adolescent female presenting with Turner-like syndrome with primary amenorrhea and Tanner stage 1 breast development. Karyotype showed one X chromosome and a minute pericentromeric fragment of Y chromosome without any functional Y genes in all the cells, unlike a mosaic pattern, represented as 46,X,der(Y)del(Y)(p11.2)del(q11.2). Laparoscopic bilateral gonadectomy was performed due to presence of Y chromosome material and histopathology confirmed gonadoblastoma with a focus of dysgerminoma of the right ovary. A robotic-assisted surgical staging for dysgerminoma was performed which was confirmed to be negative for malignancy. This points at the putative genes for gonadoblastoma to be present around the centromere of the Y chromosome.
