[Management of thyroid nodule].

The widespread use of imaging (ultrasonography, doppler, CT) has led to an "epidemic" of thyroid nodules. More often observed in women, the management of thyroid nodules is a recurring problem in routine clinical practice. Fine needle aspiration cytology (FNAC) of suspicious nodule on ultrasound is the most reliable tool to select patients requiring surgery. Scintigraphy is not accurate enough to predict malignancy, the small size of a nodule is not a reassuring factor for the clinician and the prevalence of cancer is as frequent for isolated nodules or multinodular goiter. Thyroid cancer corresponds to 9 to13% of nodules undergoing FNAC and prognosis is good for differentiated carcinomas.
