ABSTRACT
Congenital adrenal hyperplasia is generally associated with oligo-amenorrhea, and its presentation with polymenorrhagia is rare. Here we present a case of an Asian female who presented with polymenorrhagia since menarche, increased body hair growth and enlargement of clitoris for 7-8 years. Examination revealed a normal Body Mass Index, moderate hirsutism, Tanner 5 breasts and significant clitoromegaly. Serum testosterone and 17-hydroxyprogesterone levels were elevated. Ultrasonography revealed normal adrenal glands and polycystic ovaries. adrenocorticotropic hormone stimulation test uncovered borderline cortisol deficiency. Oral dexamethasone was commenced and six months later, she showed improvement though there was no change in hirsutism or clitoromegaly. The case is unique because it presented with polymenorrhagia. Also, such phenomenally high 17-hydroxyprogesterone levels are not expected in non-classic congenital adrenal hyperplasia.
