Vlaški Jovan, Katanić Dragan, Kavečan Ivana, Dautović Slavica, Vorgučin Ivana

A girl with congenital adrenal hyperplasia due to 21 hydroxylase (CYP 21, p450c2l) deficiency is the reviewed case. The clinical features (virilisation, clitoromegaly, rapid somatic growth, accelerated skeletal maturation) and laboratory find­ings (high levels of plasma 17hydroxyprogesterone, corticotrophin - ACTH, testosterone and dehydroepiandrostenedione -DHEA, low level of plasma cortisol, high level of urine 17- ketosteroids, synacthen and luteinising hormone releasing hor­mone - LHRH test) and the response to hydrocortisone therapy pointed at heterosexual gonadotrophin independent puberty due to irregular production of cortisol caused by 21 hydroxylase deficiency that leads to elevated ACTH and 17-hydroxy progesterone secretion and makes congenital adrenal hyper­plasia as entity. The six-month therapy resulted in the clinical and laboratory findings improvement, such as the decreased annual growth of body height and the stagnation in the devel­opment of the secondary sexual features.
