[Thyroid nodules]

Abstract

Thyroid nodules are commonly encountered in clinical practice. They are present in 4 to 7% of the population by neck palpation and 30 to 50% by ultrasonography. Most are benign and could be neglected by the clinician and his patient. However, 5% of nodules are malignant, requiring surgical treatment; therefore, an exhaustive evaluation is needed. The diagnostic approach includes physical examination, laboratory analysis, ultrasonography, radioisotope imaging, and fine needle aspiration. This article, based on the literature and the authors'experience, provides recommandations for thyroid nodule management.
