title: [Late discovery of female pseudo-hermaphroditism by complete blockade 21-hydroxylase (author's transl)].
abstract: The authors report on a case where complete blockade of 21-hydroxylase was discovered in a 40-year-old subject. They emphasize the usefulness of urinary 17-ketosteroid and 17-OH progesterone assays in the diagnosis of pseudo-hermaphroditism. In contrast to major hyperandrogenism, the HY antigen test is negative, since the percentage of fluorescent lymphocytes is even lower than in the normal female population.
