Intraductal papillomas of the breast are benign lesions with an incidence of approximately 2-3% in humans.[1]
Two types of intraductal papillomas are generally distinguished. The central type develops near the nipple. They are usually solitary and often arise in the period nearing menopause. On the other hand, the peripheral type are often multiple papillomas arising at the peripheral breasts, and are usually found in younger women. The peripheral type are associated with a higher risk of malignancy.[2]
They are the most common cause of bloody nipple discharge in women age 20-40 and generally do not show up on mammography due to their small size, so the next step in treatment would be a galactogram to guide the subsequent biopsy.
The masses are often too small to be palpated or felt. A galactogram is therefore necessary to rule out the lesion.
Excision is sometimes performed.[3] Microdochectomy/microdochotomy (removal of a breast duct) is the treatment of choice.
