Solitary thyroid nodule. 2. Selective approach to management.

Ordinarily, the history and physical examination and routine tests, including thyroid function tests, iodine 123 or technetium Tc 99m scans, and echography, will determine the best therapeutic approach to a solitary thyroid nodule. In the case of an asymptomatic, hypofunctional solid nodule, thyroid hormone suppression and fine-needle aspiration biopsy may be necessary to further delineate the best therapy.
