Mandibular involvement of plasmacytoma - Uncommon case report of rare entity.

Solitary plasmacytoma (SP) is an early-stage plasma cell malignancy that is in between monoclonal gammopathy of undetermined significance (MGUS) and multiple myeloma (MM) along the spectrum of plasma cell disorders. SPs can be divided into 2 groups according to location: solitary bone plasmacytoma (SBP) - these occur most commonly in the vertebrae and secondarily in long bones, and extramedullary plasmacytoma (EMP) - these encompass all nonosseus SPs. The etiology is still unknown, and they generally display a destructive course with preponderance of males.
