Abstract PDF: The 46, XX male syndrome is rare disease that is characterized by a phenotypic male who has a 46, XX female karyotype. Since the first report by de la Chapelle and associates in 1964, several cases have been reported, but it is still a rare entity. Recently we examined a 20-year-old XX male who had the symptoms of gynecomastia, an infantile appearance of the external genitalia, scanty pubic hair, no Adams apple, and no axillary hair. We presently describe a patient with the 46, XX male syndrome who showed a 46, XX karyotype on chromosomal study and review the literatures.
