Intraductal papilloma of the breast
Diagnosis in short

Intraductal papilloma. H&E stain.
Synonyms breast papilloma
LM true papillae (nipple-shaped structures with fibrovascular cores), intraductal proliferation of epithelial and myoepithelial elements, +/-hyalinization
LM DDx intraductal papilloma with florid epithelial hyperplasia, intraductal papilloma with atypical ductal hyperplasia, intraductal papilloma with ductal carcinoma in situ, invasive papillary carcinoma of the breast.
Site breast
Signs +/-nipple discharge
Prevalence common
Prognosis benign
Treatment usually excision

Intraductal papilloma of the breast, also papilloma and intraductal 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.
  • When many ducts are involved the process is termed 'papillomatosis'.

DDx:

† Size criteria are different in papillomas.
