title: Incidental treatment of nipple discharge caused by benign intraductal papilloma through diagnostic Mammotome biopsy.
abstract: OBJECTIVE
  The purpose of this study was to evaluate imaging-guided vacuum-assisted mammotome biopsy as a minimally invasive method of obtaining a satisfactory diagnosis and eliminating the bothersome symptoms in patients presenting with nipple discharge.
  
  
  METHODS
  Forty-nine women who presented with nipple discharge and who had final pathologic diagnoses of papillary lesions were retrospectively identified. Fifty-six lesions were biopsied in this group. The examinations included mammography, ductography, sonography, and, if possible, percutaneous biopsy. All lesions were centrally located and most were superficial. Of this study group, four patients with five lesions proceeded to sonographically guided automated core biopsy, and 38 patients with 44 intraductal lesions identified by sonography advanced to sonographically guided biopsy with an 11-gauge mammotome probe. One patient underwent stereotactic 11-gauge mammotome biopsy. Patients not advancing to sonographically guided biopsy were those with masses either in the nipple or nipple-areolar complex (five patients), one patient with no identifiable lesion at sonography, and one directly referred for open surgical biopsy.
  
  
  RESULTS
  In all biopsied patients, satisfactory tissue for diagnosis was obtained. In patients biopsied with the mammotome probe, follow-up at a mean time of 13 months revealed resolution of the presenting problematic discharge in 97.2% of patients. Complications were mild and infrequent. Only one of 50 percutaneously biopsied lesions was not benign and required subsequent surgery.
  
  
  CONCLUSIONS
  Papilloma excision with percutaneous biopsy allows safe and accurate tissue analysis and a high probability of terminating the symptomatic nipple discharge.
