[Extramedullary plasmocytoma of the larynx].

Extramedullary plasmacytomata (EMP) are rare malignant neoplasms composed of plasma cells, 90 percent of which occur in the neck and head area, but generally representing only 1 percent of tumors of that location. The paper report a case of extramedullary plasmacytoma of the larynx, in a 62-year-old man. We also review the different malignant plasma cell dyscrasias, paying special attention to the EMP, given its predilection for the upper aerodigestive tract.
