A subareolar abscess is an abscess or growth on the areolar gland, which is located underneath or beneath the areola (the circular area of darker pigmentation around the nipple) of the breast.
The cause of a subareolar abscess is a blockage of the small glands or ducts under the areola, with development of an infection under the skin.
This is an uncommon problem that affects younger or middle-aged women who are not breast-feeding, unlike most types of infections in the breast. There are no known risk factors.
