title: [Classification and clinical study of plasma cell mastitis under breast duct endoscope].
abstract: OBJECTIVE
  To evaluate the clinical significance of breast duct endoscope for plasma cell mastitis.
  
  
  METHODS
  Breast duct endoscope was performed on 250 patients with nipple discharge. The characters of 95 cases of plasma cell mastitis under the breast duct endoscope were analyzed and studied.
  
  
  RESULTS
  Among the 95 cases with plasma cell mastitis, 21 were in type I, 43 in type II, 18 in type III and 13 in type IV. Eighty-three cases were treated with no-operation treatment, and 45 completely released, 38 partly released. There were 5 cases with middle to serious atypical hyperplasia in 12 cases treated with operation, that were all confirmed by pathological examination.
  
  
  CONCLUSIONS
  In patients with plasma cell mastitis, clear diagnosis can be made through breast duct endoscope, and the breast duct with lesions could be positioned. It is a necessary assistant method for patients to avoid biopsy or decrease the biopsy range.
