title: Pure yolk sac tumor of the ovary with mosaic 45X/46X + mar Turner's syndrome with a Y-chromosomal fragment.
abstract: A pure yolk sac tumor (endodermal sinus tumor) of the dysgenetic gonad developed in a 23-year-old woman whose karyotype was mosaic 45X/46X + mar Turner's syndrome is reported. Molecular biological studies showed that the patient's DNA contained a fragment of Y chromosome. This case seems to be extremely rare case of developing a pure yolk sac tumor in a patient with mosaic Turner syndrome with a Y-chromosomal fragment.
