Intraductal Papillomas

Intraductal papillomas are unusual growths of gland tissue, fibrous tissue and blood vessels. These small tumors often found in the large milk ducts near the nipple, and can cause bloody discharge from the nipple. Intraductal papillomas are also found in small ducts in areas of the breast further from the nipple. In this case, there will often be several growths. Papillomas occur most frequently in women between the ages 35-55.

The symptoms of intraductal papillomas include:

• Pain in the breast
• Nipple discharge
• Staining of the bra or clothing
• A lump in the breast
• Breast enlargement

In cases where the papilloma is large enough to be felt, a needle biopsy can be conducted. Other tests include a mammogram, although mammograms do not always reveal papillomas. An ultrasound may be conducted, or a test called a ductogram. During a ductogram, contrast dye is injected into the affected duct, and an x-ray is taken. In some cases, a biopsy is necessary to make a definitive diagnosis and rule out the presence of cancer.

The usual treatment is to remove the papilloma and a part of the duct that it is found in, usually through an incision at the edge of the areola, which is the darker colored area around the nipple.

Providers are not certain what causes intraductal papillomas, and risk factors for this condition are not currently known.
