ABSTRACT
SUMMARY Medullary thyroid carcinoma (MTC) is a relatively rare neuroendocrine tumor that originates in the parafollicular C cells of the thyroid gland. It is characterized by the synthesis and secretion of calcitonin. Usually, serum calcitonin is used as part of the diagnosis and follow-up of these patients. Few cases of MTC with negative calcitonin have been reported worldwide, whose diagnosis is a clinical challenge.
