摘要: Bilateral breast tumors, a malignant phyllodes tumor in the right and an invasive lobular carcinoma left breast, occurred 47-year-old woman with 46XX/46XY mosaic karyotype her peripheral blood lymphocytes intersex external genitalia. Postmortem examination revealed bilateral ovotestis. Three of patient's sisters also had cancer. In situ hybridization Y-specific probe Y-chromosome-specific signal both suggesting that clonal origin tumors this patient was Y-containing cells. Androgen-receptor polymorphism monoallelic X chromosome pattern recurrent tissue taken at autopsy, addition to loss heterozygosity demonstrated locus TP53. The slippage CA repeats shown loci D5S82 D11S527. mechanistic basis for occurrence XX/XY mosaicism, familial clustering cancer is still unknown. present study, however, suggests sex abnormality may have modified phenotype manner similar Klinefelter's syndrome (though phenotypically male) Y promoted cell growth.
