Solitary plasmacytoma of the mandible: A rare case report.

Plasmacytoma is a monoclonal, neoplastic proliferation of plasma cells that usually arises within bone marrow or soft tissue sites. It can involve either a single bone (solitary) or multiple bones. Solitary plasmacytoma has a predisposition for the red marrow-containing axial skeleton and is most frequently seen in the thoracic vertebrae, followed by the ribs, sternum, clavicle, or scapula. Its presence in the jaws is extremely rare. We present a case of a 54-year-old female with a well-defined radiolucency of the body region of the mandible later diagnosed as solitary plasmacytoma.
