Background: There are few reports describing chromosomal abnormalities in transexuals. In rare cases, transsexualism and sexual chromosomal multiplicity coexist. Six cases of male-to-female transsexuals with 47,XYY chromosomal pattern have been previously reported, We have not encountered any female transsexual cases with 47,XXX karyotype in the literature.
