Invasive Hürthle cell carcinoma of the thyroid: natural history and management.

Debate surrounds the natural history and appropriate management of Hürthle cell neoplasms of the thyroid. Some of the uncertainty stems from difficulty in the differentiation of benign from malignant lesions. We report the presentation, management, and outcome of patients with invasive Hürthle cell carcinoma who were examined at this institution between 1946 and 1971. We believe that our review allows us to make reasonable recommendations concerning the management of patients with this type of carcinoma.
