Medullary thyroid cancer (MTC) is a neuroendocrine tumor derived from parafollicular cells or C cells of the thyroid gland. It represents 1-2% of all thyroid cancers in the United States1, 2 . The production of calcitonin is characteristic of this tumor. We present the case of a 22-year-old female patient with a known morbid history of nodular thyroid disease diagnosed 7 years ago with irregular follow-up, who was biopsied and reported Bethesda V suspicious for medullary carcinoma.
