Thyrotoxicosis: a rare presenting symptom of Hurthle cell carcinoma of the thyroid.
Hurthle cell carcinoma of the thyroid is a rare type of thyroid neoplasm. The most common clinical presentation is a single palpable thyroid nodule. The neoplasm typically presents as a nonfunctioning or cold nodule on a Tc-99m sodium pertechnetate or radioiodine thyroid scan. We report a case of Hurthle cell carcinoma of the thyroid in a woman presenting with thyrotoxicosis. The Tc-99m thyroid scan was also interesting in that the nodule was a hot or hyperfunctioning area, resulting in a rare scintigraphic finding in a rare tumor. Clinicopathologic aspects and related issues are further discussed.
