[Congenital virilizing adrenal hyperplasia due to 11 beta-hydroxylase deficiency. Study of eleven cases (author's transl)].

Eleven cases of congenital virilizing adrenal hyperplasia are studied. This study leads to point out some peculiar characteristics: virilization of external genitalia in girls is most usually important; arterial hypertension is delayed, usually after some years; plasma androgens and desoxycortisol are highly elevated; plasma 17-hydroxyprogesterone is slightly elevated and this may be misleading; good results of treatment which must preferably use hydrocortisone since plasma cortisol is sometimes low; long-term risks in treated children include chronic hypertension in both sexes, advanced puberty in girls and pubertal gynecomastia in boys.
