Abstract
Mucoepidermoid carcinoma (MEC) of the thyroid gland is a rare neoplasm with 40 cases reported in the world literature to date. Controversy surrounds the treatment of this rare neoplasm. It has been described as a low-grade indolent tumor that rarely metastasizes and only recurs locally without morbidity. Suggested treatment has consisted of a lobectomy or subtotal thyroidectomy. We report a case of a 63-year-old woman with a 15-year history of a multinodular goiter with a dominant left lobe nodule. Fine-needle aspiration was inconclusive. The patient opted for a total thyroidectomy. Final pathology yielded a diagnosis of mucoepidermoid carcinoma. We propose that despite its low-grade appearance the morbidity and mortality associated with its ability to locally recur and metastasize justify the need for more aggressive surgical therapy.
