Abstract
• We studied two cases of hyperfunctioning thyroid nodules in children. A 9-year-old girl and an 11-year-old girl had thyroid masses in otherwise nonpalpable thyroid glands. Scintiscan showed hyperfunctioning thyroid nodules. The former patient had elevated values for T4 and T3, and plasma thyrotropin (TSH) level failed to respond to stimulation with thyrotropin releasing hormone (TRH), whereas the latter patient had normal values for T4 and T3 and plasma TSH response to TRH was normal. After the surgical removal of nodules, scintiscan exhibited radioactivity in the contralateral lobe of the thyroid gland in the former and in the ectopic thyroid tissue in the latter. Results of microscopic examinations of thyroid nodules were consistent with adenomatous goiter. (Am J Dis Child 134:961-963, 1980)
