Plasmacytomas are relatively rare tumors that often appear in the head and neck region. They are characterized by monoclonal proliferation of plasma cells. Three pathological forms of plasma-cell tumors are recognized as extramedullary plasmacytomas (EMP), solitary plasmacytomas of bone and multiple myelomas (MM). EMPs account for 5% of all plasmacytomas. The incidence of EMPs in males is nearly threefold higher than in females, especially in the 5th -6th decades of life. Approximately 80% of EMPs arise submucosally in the head and neck region, mostly in the sinonasal and nasopharyngeal areas. Three cases of EMPs of the head and neck are presented in this manuscript, with the emphasis on the clinical, radiological, pathological features and management of these tumors.
