title: [Common benign breast tumors including fibroadenoma, phyllodes tumors, and papillary lesions: Guidelines].
abstract: OBJECTIVE
  To provide guidelines for clinical practice from the French College of Obstetrics and Gynecology (CNGOF), based on the best evidence available, concerning common benign breast tumors: fibroadenoma (FA), phyllodes breast tumors (PBT), and papillary lesions (BPL).
  
  
  METHODS
  Bibliographical search in French and English languages by consultation of PubMed, Cochrane and international databases.
  
  
  RESULTS
  In case of percutaneous biopsy diagnosis of FA, clinico-radiologic and pathologic discordance or complex FA or proliferative lesions or atypia with FA, a family history of cancer, it seems legitimate to discuss management in a multidisciplinary meeting. When surgery is proposed for FA, periareolar compared to direct incision is associated with more insensitive nipple but better aesthetic results (LE4). When surgery is proposed for FA, indirect incision is preferable for better cosmetic results (Grade C). Techniques of percutaneous destruction or resection can be used (Grade C). The WHO classification distinguishes three categories of phyllodes tumors (PBT): benign (grade 1), borderline (grade 2) and malignant (grade 3). For grade 1 PBT, the risk of local recurrence after surgical excision increases when PBT lesion is in contact with surgical limits (not in sano). After in sano resection, there is no correlation between margin size and the risk of recurrence (LE4). For grade 2 PBT, local recurrence after surgical excision increases for margins under 10mm margins (LE4). For grade 1-2 PBT, in sano excision is recommended. For grade 2 PBT, 10-mm margins are recommended (Grade C). No lymph node evaluation or neither systematic mastectomy is recommended (Grade C). Breast papillary lesion (BPL) without atypia, complete resection of radiologic signal is recommended (Grade C). For BPL with atypia, complete excisional surgery is recommended (Grade C).
