We report a 10-year-old male patients with the predominant karyotype 46,XX. In only one cell of the testis culture a metaphase with 47,XX+G was found. The theories of etiology of XX-males and the reported cases of XX/XXY-mosaics in the literature were discussed.

✦ Synopsis
Three males with a 46,XX karyotype are described. In two of them, evidence of a Y-containing line was found. In the first case, 1 of 500 lymphocyte metaphases was 48,XXY. In the second, 1 of 400 oral mucosa cells contained a Y body. The proportion of low-grade XX/XXY mosaics found among XX males now stands at about 17%.
