Summary
Plasmacytomas are tumors that results from monoclonal proliferation of plasma cells They are subdivided into two subtypes based on their origin into Solitary Plasmacytoma of Bone (SPB) and Extramedullary Plasmacytoma (EP) [1]. Case Presentation post auricular swelling measuring 3×8cm (Figure 1). A 53-year-old male presented to the emergency room with three months of progressive swelling in the right post auricular region. Patient is on oral hypoglycemic medication and insulin, and he is a smoker He was just worked up for multiply spinal lytic lesions which came to be multiple myeloma. Figure 2a: Computed tomography (CT) axial cut of temporal bone showing multiple bony lytic lesions with right post-auricular swelling with evidence of destruction of the mastoid cortical bone. On following up the patient, regression in the swelling size was noticed few weeks after starting chemotherapy treatment (Figure 3).
