Abstract:
Extramedullary plasmacytoma (EMP) represent 3% of plasma cell neoplasms. Approximately 80-90% of EMPs involve the mucosa-associated lymphoid tissue of the upper airways and 75% of these involve the nasal and paranasal regions, while renal or retroperitoneal infiltration is very rare. EMPs are highly radiosensitive, with excellent results. The local control rate of radiotherapy can reach 90-97% and the 5-year overall survival rate can be 57-61%. EMP has an indolent course and the prognosis is generally favorable, with 70% of the patients remaining disease free for 10 years. However, about 30% may progress to plasma cell myeloma or relapse. Here, we report a case of a huge retroperitoneal solitary extramedullary plasmacytoma that grew rapidly.
