Extra-medullary plasmacytoma is a rare tumor, resulting from the malignant proliferation of particular B lymphocytes, the plasma cells. However, there are localized forms, divided into solitary bone plasmocytoma (POS) and extramedullary plasmocytoma (EMP). The incidence is about 3-4% of all plasmocytic neoplasms. The median age of EMP presentation is 55 years with male predominance (75% of cases). The majority of cases of EMP (80% of cases) reported in the literature are in the head and neck [3], particularly in the upper aero-digestive tract and nasosinus. His treatment is based on chemotherapy, radiotherapy or surgery for some locations. His prognosis depends essentially on the risk of progression to multiple myeloma.
