Solitary extramedullary plasmacytoma: A rare gingival lesion

Abstract

Plasma cell tumors consist of extramedullary plasmacytoma (EMP), multiple myeloma (MM), and solitary bone plasmacytoma (SBP). EMP is defined as neoplastic proliferation of plasma cells in soft tissues. It presents as a solitary discrete mass either in soft tissue as EMP or in bone as SBP or as disseminated MM. It is a very rare manifestation. It accounts for <1% of all head-and-neck malignancies with oral cavity being the rarest.
