title: Carcinoma in hyperfunctioning thyroid nodule in recurrent hyperthyroidism.
abstract: A patient with an invasive thyroid carcinoma located within a hot thyroid nodule is reported. Only four similar cases have been described in the literature. It is emphasized that a hot thyroid nodule per se should not be used as an argument against the diagnosis of thyroid carcinoma.
