Extramedullary plasmacytoma (EMP) is a rare plasma cell neoplasm occurring anywhere in the body. Paranasal sinus is the most commonly involved site of head and neck region, and then nasal cavity, oropharynx on the decreasing frequency. EMP of larynx is quite rare and only two cases of EMP were reported to have occurred in the epiglottis and the false cord of larynx, respectively, in the Korean literature. We report an unusual case of EMP occurring in the arytenoid that was treated by surgical excision.
