Hirsutism is an endocrine condition affecting females with growth of unwanted, male-pattern hair secondary to excess androgen activity. The most common cause of hirsutism in females is PCOS (Polycystic ovarian syndrome). Other causes are fairly rare including adrenal and ovarian androgen producing tumours. In 3% of cases no cause of hirsutism is found and these are termed idiopathic1. We describe a unique case of a 22-year-old presenting with elevated DHEAS levels with no source identified on imaging. She achieved menarche at age of 13 followed by irregular scanty menstrual cycles and development of excess hair on her back, chin, chest, abdomen, shoulders and inner thighs. Her mother and sister also have hirsutism. Initially she was treated with OCP which did not help with the symptoms. She never complained of acne. She has never been sexually active.

On examination, she had marked hirsutism of the areas mentioned above. Her breast development was at Tanner stage 4. BMI of 27 and BP was 133/77.

Her biochemistry showed elevated DHEAS of 16.6 umol/L with serum Androstenedione of 5.8 nmols/L and normal serum testosterone of 1.5 nmol/L, rest of the endocrine work up including electrolytes, ODST for Cushing’s, 17-OH progesterone for CAH, serum prolactin, LH, FSH, progesterone, TFTs, 24 hours urinary steroid profile were all unremarkable. Serum ACTH was 16 ng/L. A transabdominal US did not demonstrate features typical of polycystic ovaries and an endometrial thickness of 4 mm. A dedicated MRI of adrenals glands did not demonstrate any pathology.

The above case illustrates a challenging case of elevated DHEAS causing hirsutism and oligomenorrhea but no adrenal or ovarian pathology identified on imaging. Radetti et al describe a similar case of isolated DHEAS elevation in a 17-year-old male2. We recommend that idiopathic elevation in DHEAS should be considered as a rare differential for hirsutism and oligomenorrhea in women.
