Intraductal Papilloma

Intraductal papillomas are small, tiny wart-like growths in the breast’s milk ducts and are non-cancerous. They are common between the ages of 35 to 55 years.

There are 3 types of papillomata:

1. Solitary intraductal papilloma which can present as a single lump near the nipple and can cause nipple discharge.
2. Multiple papillomas may present as groups or clusters of small growths, farther away from the nipple and may not cause nipple discharge.
3. Multiple papillomatosis are very small groups of cells inside the ducts and they are more scattered.

Risk Factors

There are no known risk factors.

Symptoms

​It may cause a nipple discharge. If it is near or beside the nipple a small lump may be felt.

Diagnosis

​Diagnosis is made on clinical breast examination and breast imaging, including mammograms and breast ultrasound. Biopsy is usually recommended to confirm the diagnosis.

Treatments

​Surgery may be necessary to remove the papilloma and affected part of the milk duct. This is usually curative and presents a good outlook. Vacuum-assisted core needle biopsy (VAB) is an alternative option used for these lesions.
