Abstract

Jivago Da Fonseca Lopes*, Laydner JP, Andrade LB, Fuhrmann DA, Romani F and Weinert LS

Medullary thyroid carcinoma (CMT) is a neoplasm of the parafolicular cells of the gland, associated with a poor prognosis. It usually leads to increased levels of calcitonin (CT) and carcinoembryonic antigen (CEA), however there is a report in the literature of atypical presentation, associated with non-secretion of CT. We will present the case of a 56-year-old patient with CMT and normal CT levels, with a subsequent literature review on the topic.
