We report a case of a 16 years old girl who presented sequentially with primary amenorrhoea, hypertension and hypokalaemia. Eight years later, she was finally diagnosed with 17alpha-hydroxylase deficiency congenital adrenal hyperplasia. Previous antihypertensive medications were stopped. Hydrocortisone alone successfully maintained normotension and normokalaemia.
