Management of sub-areolar abscess and mammary fistula.

Sub-areolar abscess is a form of chronic non-lactational mastitis often presenting in young women at the areolar margin as a recurring discharge or painful infection. Incision and drainage is inadequate and will be followed by recurrence unless the major duct leading from the abscess to the nipple is identified and laid open. Three cases are presented to illustrate this problem and its management.
