Pseudohermaphroditis, with testes and a 46, XX karyotype.
A 14 4/12-year-old white girl, evaluated for progressive virilization and clitormegaly, was found to have the unusual combination of a 46, XX karyotype, well-developed Mullerian structures, and dysgenetic testes with Leydig cell hyperplasia. Although there have been previous case reports of 46, XX males, in all of these patients development of the Mullerian ducts had been suppressed. When contemporary classifications of human disorders of sexual differentation were reviewed, no report of a similar patient was found. We speculate that the genotype and phenotype in our patient correspond to the genetic intersexuality of the hornless goat, thereby raising the possibility that the human autosome may play a role in the control of sexual development.
