Abstract
A case of extramedullary plasmacytoma originating from the nasopharynx is reported. A 32-year-old female complained of a left ear fullness. A smooth, elastic soft mass was found in the left Rosenmullar fossa. Biopsy of the lesion showed the mass consisted of well-matured plasma cells. The cells were found to be neoplastic as they were positive for monoclonal lg G-λ.
We reviewed 123 cases of extramedullary plasmacytomas reported in Japanese literatures including our case. Primary therapy is important for the management of the extramedullary plasmacytomas. Although we were obliged to treat by surgical resection alone in our case, it should be recommended that they are intially treated by combined therapy including surgical resection, radiation therapy, and/or chemotherapy.
