title: Plasmacytoma masquerading as an abscess.
abstract: Plasma cell neoplasia is a lymphoid neoplastic proliferation of B cells and has been classified as multiple myeloma, solitary plasmacytoma, and extramedullary plasmacytoma. Extramedullary plasmacytoma is defined as neoplastic proliferation of plasma cells in the soft tissue. Extramedullary plasmacytoma of the head and neck is very uncommon tumors, representing approximately 0.4% of all head and neck malignancies; amongst them, plasmacytoma of the maxilla is extremely rare. We present a case of a 70-year-old male with swelling on the right middle third of the face, mimicking an abscess, but proven to be extramedullary plasmacytoma. This report discusses the clinical, radiographic, histological, and immunohistochemical features of extramedullary plasmacytoma.
