We present two cases of an unusal localised extramedullary plasmacytoma with a long survival period: a 42-year-old woman with left temporal and a 25-year-old woman with left parietal intracranial plasmacytoma. The tumor masses were totally removed in both patients and their histological, histochemical (PAS and methyl green pyronin positive granules) and immunohistochemical (positive light chains mostly lambda, and negative stains for GFAP, NSE and S-100 protein) properties showed that the tumor tissues consisted of monoclonal population of plasma cells. Our cases were diagnosed as solitary cerebral plasmacytomas since the presence-of underlying multiple myeloma has been ruled out by the clinical, laboratory, radiographic and immunological investigations. Postoperatively the patients were given 40 Gy to the whole cranium and additional 20 Gy focused on the tumor site. Complete remissions were achived 7.5 and 5.5 years, respectively.
