3q27 Aberrations in a Childhood Ovary Teratoma With Associated Malignant Germ Cell Component

Cytogenetic Studies of childhood ovary tumors have been poorly described. in the present article, the cytogenetic findings of an ovarian teratoma with malignant germ cell (yolk-sac) component occurring in an 8-year-old female are detailed. GTG-banding showed a karyotype of 46,XX, t(3;20)(q27;q13.3) [4]/46,XX, del3q27 [3]/46,XX [30]. Previous Studies have demonstrated common sites of loss of heterozygosity at 3q27-q28 region in different types of cancer, suggesting the presence of tumor Suppressor genes within this region.
