Extramedullary Plasmacytoma of the Gingiva

Extramedullary plasmacytoma is defined as neoplastic proliferation of plasma cells in soft tissue. It accounts for up to 3% of all plasma cell tumors. Approximately, 90% of extramedullary plasmacytomas are found in the head and neck region commonly affecting the nasal cavity, paranasal sinuses, tonsillar fossa, and oral cavity. Radiotherapy is the common modality of treatment with or without adjuvant chemotherapy. We report a case of extramedullary plasmacytoma of the gingiva.
