FIGUEROA ZEVALLOS, Víctor; CASTRO LA ROSA, Haydee  and  TORRES ARONES, Esperanza. Pure yolk-sac tumor with XO/XY Turner’s syndrome mosaicism. Rev. peru. ginecol. obstet. [online]. 2013, vol.59, n.4, pp.295-300. ISSN 2304-5132.

Turner’s syndrome is a genetic disorder caused by lack of an X chromosome. In some cases it is present with XY mosaicism, with increased risk of malignant gonadal tumors. It is important to determine the presence of the Y chromosome to perform prophylactic removal of the dysgenetic gonads. We present the case of a patient with Turner’s syndrome 45,X0/46,XY mosaicism associated to pure giant yolk sac tumor. This association of malignancy in a patient with mixed gonadal dysgenesia is extremely rare.

Keywords : Turner’s syndrome; mosaicism; gonadal dysgenesia gonadal; yolk sac tumor.
