[A case of virilizing adrenal cortical adenoma whose steroid profile evokes a partial 21-hydroxylase deficiency (author's transl)].
The C19 and C21 urinary steroids from a virilizing adrenal tumour with high levels of plasma 17 alpha-hydroxyprogesterone and its urinary metabolites have been identified and quantitated gas chromatography and mass spectrometry of sephadex fractions of the total urinary extract. A of the fifty-five identified steroids thirteen were compounds not found before in such a case. The actiology of the apparent 21-steroid hydroxtlase deficiency is discussed at the light of these analytical results and of the hormonogenesis enzymatic induction of the tumour biopsy.
