Intraductal Papilloma with Atypia

Intraductal Papilloma with Atypia

  • Although a solitary intraductal papilloma is benign:
    • When a papillary lesion with atypia is identified on core biopsy:
      • Surgical excisional biopsy is recommended to rule out an associated in situ or invasive cancer:
        • Studies have demonstrated an upstage rate of 22% to 67% when atypia is present:
          • But only 3%to 9% in the absence of atypia
  • MRI is available as an additional diagnostic tool:
    • A negative MRI would not obviate the need for excisional biopsy to exclude malignancy since it cannot reliably distinguish benign from malignant papillomas
  • A short-term follow-up could be considered appropriate:
    • For an intraductal papilloma without atypia on core biopsy if these findings are considered concordant with the clinical presentation
