title: [Androgen-producing adrenal adenoma in an 18 year-old woman: diagnosis by gas-chromatographic steroid analysis, histology and postoperative course].
abstract: Gas-chromatographic analysis of the urinary steroids in an 18 year-old girl with primary amenorrhoea and hirsutism revealed markedly elevated excretion of androsterone, etiocholanolone, dehydroepiandrosterone, and androstendiole, both under basal conditions and after oral dexamethasone (0.5 mg q.i.d. for three days). Adrenal scintigraphy revealed the presence of a tumour of the right adrenal gland, which was subsequently removed by unilateral adrenalectomy. Histologically, the tumour showed marked anisocytosis, but since there was no evidence of capsular or angioinvasion or of mitotic activity, it was classified as an adrenocortical adenoma. Postoperatively the patient showed regression of the virilizing syndrome and normal menstrual bleeding. Urinary steroid excretion has remained normal for four years after adrenalectomy. Androgen-producing tumours must be considered as a possible cause of hirsutism in young females and should, thus, be excluded in each case. Analysis of urinary steroids by gas chromatography is a valuable tool in accomplishing this task.
