Tumor Size Predicts Malignant Potential in Hürthle Cell Neoplasms of the Thyroid

Abstract

Tumor size correlates directly with malignant potential in patients with Hürthle cell neoplasms of the thyroid. Among our patients, malignancy was not present in any tumors 2 cm or smaller and was present in all tumors larger than 6 cm. Because the risk of malignancy is greater than 50% in patients with a tumor larger than 4 cm, consideration should be given for an initial total thyroidectomy in these patients.
