Intraductal papilloma, also papilloma, is a relatively common benign pathology of the breast.

General

  • May cause nipple discharge.[1]
  • Similar to papillary hidradenoma of the vulva.
  • Usually excised to exclude malignancy.
    • Risk very low if not associated with a mass or suspicious radiologic findings - conservative management may be reasonable.[2]

Microscopic

Features:

  • True papillae - nipple-shaped structures with fibrovascular cores.
  • Intraductal proliferation of epithelial and myoepithelial elements.[3]

Notes:

  • Lacks florid hyperplasia.[4]
  • May degeneration and hyalinize to form a sclerosing papilloma.

DDx:

† Size criteria are different in papillomas.

Images

  • Papillary hidradenoma - low mag. (WC/Nephron)

  • Papillary hidradenoma - very high mag. (WC/Nephron)
