Summarytoggle arrow icon

Intraductal papilloma is a tumor that arises from the epithelium of the lactiferous ducts, with a peak incidence between 30–50 years of age. Solitary papillomas (central papillomas) are the most common cause of bloody or serous nipple discharge and are often associated with a palpable retroareolar mass; they are typically benign. Multiple papillomas (peripheral papillomas) are usually asymptomatic and diagnosed incidentally; they are often associated with atypia, DCIS, or invasive breast cancer. Characteristic features of intraductal papillomas on age-appropriate breast imaging include a well-defined intraductal mass and calcifications. Image-guided core needle biopsy is recommended in all patients for diagnostic confirmation and to assess for cellular atypia. Intraductal papillomas without atypia can be managed expectantly. Surgical excision to rule out concomitant malignancy is recommended for patients with intraductal papillomas with atypia; these patients should undergo further risk assessment for breast cancer and be considered for prophylactic chemotherapy.

Clinical featurestoggle arrow icon

  • Solitary papilloma (also known as central papilloma)
  • Multiple papillomas (also known as peripheral papillomas)

Solitary intraductal papillomas are typically benign. Multiple papillomas are often associated with atypia, DCIS, or invasive breast cancer. [2][5]

Diagnosticstoggle arrow icon

Follow age-appropriate diagnostic workup for a palpable breast mass and/or nipple discharge (see “Breast mass” and “Nipple discharge” for details). The findings specific to intraductal papillomas are described here. Asymptomatic intraductal papillomas may also be detected incidentally.


Initial imaging [2][5][6]

Additional imaging


Breast MRI [5][10]

Core needle biopsy [5]

Treatmenttoggle arrow icon

  • Intraductal papilloma without atypia [5][10][13][14]
    • Surveillance
    • Excision may be considered for symptomatic control.
  • Intraductal papilloma with atypia [5][15]
    • Surgical excision of the affected duct(s)
    • Refer patients to oncology for further risk assessment and the possible need for prophylactic chemotherapy.

Prognosistoggle arrow icon

  • Intraductal papilloma without atypia: good prognosis
  • Intraductal papillomas with atypia: associated with an increased risk of breast cancer
