title: Criteria for excision of suspected fibroadenomas of the breast.
abstract: BACKGROUND
  Fibroadenomas are benign breast tumors; however, more aggressive lesions may mimic or arise within fibroadenomas. We sought to define criteria identifying patients who should undergo surgical excision.
  
  
  METHODS
  Patients with a preoperative diagnosis of fibroadenoma, who underwent surgical excision between 2002 and 2011, were retrospectively reviewed. Patients with final pathologic diagnosis of fibroadenoma were compared with those with non-fibroadenoma pathology.
  
  
  RESULTS
  Of the 723 patients, 681 (94%) had fibroadenomas on final pathology. The incidence of non-fibroadenoma pathology was 6% (42 patients) and included benign phylloides (23), malignant phylloides (2), atypical ductal hyperplasia (1), intraductal papilloma (5), and other benign pathology (11). No cases of adenocarcinoma were identified. Non-fibroadenoma pathology was associated with age >35, immobile or poorly circumscribed mass, size >2.5 cm, and biopsy not definitive for fibroadenoma.
  
  
  CONCLUSIONS
  Patients with age >35 years, immobile or poorly circumscribed mass, size >2.5 cm, or biopsy not definitive for fibroadenoma should undergo surgical excision.
