The human areola (areola mammae, /əˈrələ/[1][2] or /ˌæriˈlə/[2][3]) is the pigmented area on the breast around the nipple. Areola, more generally, is a small circular area on the body with a different histology from the surrounding tissue, or other small circular areas such as an inflamed region of skin.
