Introduction: Mixed adenoneuroendocrin carcinoma (MANEC) has a phenotype when neuroendocrin tumor coexists with adenocarcinoma. The incidence of MANEC has not yet been epidemiologically analyzed since it is one of the rarest types of neuroendocrine tumor, only case reports can be found in the literature. The few reported cases was all found in the gastrointestinal tract and none of them was ever decribed in the oral cavity.
Case report: 68-year–old male patient presenting with voluminous lesion in the oral cavity, below the tongue involving the floor of the mouth. CT showed a 4.5 cm large bulky resistens. Preoperative core needle biopsy suggested a neuroendocrin malignancy which has been surgically removed. Histopathologic examination revealed a MANEC tumor. He did not receive any chemotherapy. The patient is clinically and radiologically tumor-free at 17 month postoperatively.
Discussion: The optimal strategy of management of MANEC is largely unknown due to the rarity of these neoplasm. I am eager to discuss any further treatment options proposed by the participants.
