Abstract
Approximately 30 sex chromosome discordant chimera cases have been reported to date. In particular, there are few reported cases of chimerism involving coexisting normal and abnormal lineages that each carries a distinct sex chromosome complement. To our knowledge, this is the first case of sexual chimerism with a simultaneous chromosomal aneuploidy involving chromosome 8. This report represents the data from 11 years of follow-up.
