[Extramedullary plasmocytoma. Report of 5 cases].
The extramedullary plasmacytoma account for 1-2% of the total number of plasma-cell growths. 80 percent are originated on head and neck, beginning on submucous layer of the upper airways. Male are more frequent affected at sixth-seventh decade. Roentgentherapy chemotherapy is only worldwide accepted in cases of scattered disease, but when the cases are localizated the method is under assessment. Long tern follow up of patients is recommended, because there are cases which after many years of calm can evolve into a multiple myeloma. We report 5 cases: 3 women and 2 men, diagnosed as extramedullary plasmocytoma. In one of them, considered as nasal plasmacytoma, three years later was discovered an other plasmacytoma on a tibial epiphysis. The whole group was surgically treated with complementary röntgentherapy 4 of them. Afterwards no one showed multiple myeloma.
