Spontaneous regression of extramedullary plasmacytoma —A case report
A case of extramedullary plasmacytoma in the soft tissues of the posterior chest wall of an 80-year old man is reported herein. Immunofluorescence study showed that the tumor cells produced IgGλ. An M-component was also detected in the patient’s serum by paper electrophoresis. Two months following the open biopsy done to establish diagnosis, the tumor underwent spontaneous regression and the M-component in the serum also disappeared. This is the first case report of spontaneous regression of an extramedullary plasmacytoma and the probable reasons for this spontaneous regression are discussed herein.
