title: Multiple primary cutaneous plasmacytomas: an unusual presentation.
abstract: BACKGROUND
  Extramedullary plasmacytoma of the skin, a rare type of cutaneous B-cell lymphoma, is characterized by clonal proliferation of plasma cells primarily in the skin without evidence of multiple myeloma. Only about 30 cases with extramedullary plasmacytoma of the skin are reported in the literature.
  
  
  METHODS
  An 82-year-old male patient presented to our clinic with complaints of asymptomatic red nodular swelling and pain in the anterior chest wall. A dermatologic examination revealed multiple nodular lesions of varying sizes with a hard smooth surface and vivid red color. Serum protein and immunoglobulin electrophoresis, skeletal radiography, and bone marrow biopsy showed normal results in this patient. Here a rare case of multiple primary plasmacytoma localizing in the skin is reported.
