title: [Solitary extramedullary plasmocytoma of the nasal fossa and paranasal sinuses].
abstract: The clinical and morphological features of two patients with solitary extramedullary plasmacytomas of paranasal sinus and nasal cavity are presented. Patients only developed local symptomatology without features of multiple myeloma. They were treated with surgical excision and local radiotherapy. This is the treatment of choice recommended for these localized tumors. Microscopically, one tumor contained a well-differentiated plasma cell population, and the other was made up immature cells. Cytoplasmic staining for IgG was showed in both tumors for immunoperoxidase studies. However, no serum monoclone was detected at the time of diagnosis nor later. Currently, they are alive without evidence of disease 20 and 16 months, respectively, after treatment.
