title: Primary pulmonary plasmacytoma: a case report introduction.
abstract: BACKGROUND
  Extramedullary plasmacytoma is a rare plasma cell neoplasm within soft tissue and without bone marrow involvement or other systemic characteristics of multiple myeloma. Primary pulmonary plasmacytoma is a rare type of extramedullary plasmacytoma.
  
  
  METHODS
  A 48-year-old male with a tumor in the right middle ear was referred to our hospital. A routine chest X-ray was arranged and showed enlargement of the left lung hilum. His bilateral breathing sounded clear. A chest CT scan revealed a well-circumscribed mass. Pathological biopsy yielded a diagnosis of isolated pulmonary plasmacytoma.
  
  
  CONCLUSIONS
  This is the first presentation of primary pulmonary plasmacytoma with a solitary pulmonary nodule and no lymph node involvement.
