Malignancy risk in indeterminate thyroid nodules with Hürthle cells: role of autoimmune thyroiditis

Hürthle cells are modified follicular thyroid cells, whose development and proliferation have been related to different stimuli inducing cellular stress. Most thyroid aspirates containing Hürthle cells are classified as indeterminate, although the specific risk of malignancy for this subtype of atypia remains unclear. The aim of our study was to assess if the presence of Hürthle cells in indeterminate thyroid nodules correlates with the risk of...
