Plasma cell neoplasms (plasmacytoma) are discrete, solitary masses of lymphoid neoplastic proliferations of B cells. Plasmacytomas comprise three groups: multiple myeloma, solitary plasmacytoma (SP) and extramedullary plasmacytoma. SP originates as a clone of transformed malignant plasma cells in the bone marrow. SP of the jaw is a rare condition; therefore diagnosis is quite difficult and often results in misdiagnosis. MM is a lymphoproliferative disease the prognosis of which is worse than SP. SP can progress to MM in a few months to years after diagnosis. In this regard, early diagnosis of the disease is of utmost importance. This article presents two cases of SP diagnosed in the mandible and documented with clinical, radiographic and histological findings.
