Intraductal Papilloma’s

  • There are multiple types of papillary breast lesions including:
    • Benign intraductal papillomas
    • Atypical papillomas
    • Papillomas with atypical ductal hyperplasia (ADH)
    • Papillary carcinomas
  • A solitary intraductal papilloma:
    • Is a common breast lesion:
      • That can present with nipple discharge if arising in the large ducts, or
      • As a clinically occult mass on imaging if occurring in the periphery
      • Infrequently, an intraductal papilloma presents as a palpable mass
    • Typically, atypia or carcinoma in situ:
      • Is more frequently associated with intraductal papillomas in the periphery of the breast:
        • However, due to intralesional heterogeneity and fragmentation, sampling error is a concern with core needle biopsy
    • Recent studies suggest the risk of upgrade to carcinoma upon excision of an intraductal papilloma with atypia:
      • Is 21% to 37%:
        • Thus, removal of the entire lesion is sometimes required to rule out in situ or invasive cancer
    • wide margin is not required at the time of excision biopsy of a papillary lesion
