ABSTRACT
The mucoepidermoid carcinoma is a neoplasia that usually occurs at salivary glands, breast, pancreas and gastrointestinal tract. The primary occurrence on thyroid gland is rare and only 33 cases were previously published. Although the majority of cases of mucoepidermoid carcinoma of the thyroid (MECT) show a benign evolution, this paper describes a patient with an aggressive tumor. A literature review over clinical, histopathological, immunohistochemical features and histogenetic origin was discussed.

O carcinoma mucoepidermóide é um tipo de neoplasia encontrada geralmente nas glândulas salivares, mamas, pâncreas e trato digestivo. O acometimento primário da glândula tireóide é muito raro, apenas 33 casos na literatura. Embora a maioria dos casos de carcinoma mucoepidermóide de tireóide (CMET) tenha evolução favorável, o caso clínico relatado descreve uma paciente com tumor agressivo e, a partir deste relato, é apresentada revisão da literatura quanto aos aspectos clínico, histopatológico, imunohistoquímico e origem histogenética dessa neoplasia.
