[Plasmacytoma of the larynx].

Multiple myeloma is a neoplastic proliferation of the plasma cells of clonal character producing similar immunoglobulin or part of the immunoglobulin. Multiple myeloma occasionally occurs as solitary, extramedullary plasmacytoma. The location of plasmacytoma in the larynx is extremely rare. We are describing the case of the larynx plasmacytoma diagnosed for a 79 years old female patient. After histopathologic diagnosis of the laryngeal polyp the patient was examined hematologically in great detail aiming at the investigation of myeloma multiplex. No features of multiple myeloma have been found. Now the patient is under strict laryngological and hematological care.
