A 65-year old female with synchronous HIV and Extramedullary Plasmacytoma of Maxillary sinus

Extramedullary plasmacytoma in the head and neck region is a rare malignant neoplasm comprising approximately 3% of all the plasma cell neoplasms and less than 1% of head and neck tumors. This extraskeletal lesion is a unifocal, monoclonal, neoplastic proliferation of plasma cells. Some investigators believe that this lesion represents the least aggressive part of the spectrum of plasma cell neoplasms which extends to multiple myeloma. Therefore, plasmacytoma is believed to have clinical importance. We report a case of extramedullary plasmacytoma in the right maxillary sinus of a 65-year-old HIV positive female as a clinical rarity with review of the relevant literature.
