title: Primary lymphoma of the breast: unusual presentation of breast cancer.
abstract: OBJECTIVE
  To investigate 4 cases of primary lymphoma of the breast and review previous studies in a search for any preoperative characteristics that could assist the diagnosis of lymphoma of the breast.
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  University hospital, Israel.
  
  
  METHODS
  4 women.
  
  
  METHODS
  Accurate diagnosis before operation.
  
  
  RESULTS
  No special characteristics for early diagnosis of primary malignant lymphoma of the breast were found. The predominant involvement of right breast in primary lymphoma of the breast should be noted.
  
  
  CONCLUSIONS
  Even though primary lymphoma of the breast is rare, there are no laboratory or imaging signs of early diagnosis. Excisional biopsy or Tru-cut biopsy are the only correct methods of diagnosis.
