[Extramedullary manifestation of plasmocytoma in ENT].

Plasmocytomas are non-Hodgkin's tumors which occur with an incidence of 4/100,000. Malignant plasma cells in bone marrow produce monoclonal antibodies which are typically found in urine and blood samples. In rare instances plasmocytoma occur exclusively in extramedullary locations preferring head and neck region. We report about two patients with extramedullary plasmocytoma, one of them with an extremely rare triple manifestation in the upper airway.
