A Case of Multiple Myeloma with Lung Involvement

Plasmacytoma are extramedullary accumulations of plasma cells. Most extramedullary plasmacytomas are associated with the upper respiratory tract. The lung is rarely involved. We report a rare case of lung plasmacytoma with multiple myeloma. The patient is a ۶۰-year-old male who presented with chest pain and a lung mass visualized on CT scan. A preliminary diagnosis of occult lung cancer with widespread skeletal metastasis was made. The diagnosis of lung plasmacytoma with multiple myeloma was made after extensive investigations.
