Accessory breasts, also known as polymastia, supernumerary breasts, multiple breast syndrome, or mammae erraticae, is the condition of having an additional breast. Extra breasts may appear with or without nipples or areolae. Aberrant breast tissue is usually present along the milk line (extends from axilla to groin) above or below the normal breast location. Occasionally, it is found in unusual locations, such as the axilla, scapula, thigh, and labia majora. Accessory axillary breast tissue is present in approximately 2% to 6% of women. The accessory tissue may range from a subcutaneous focus of breast tissue to a full accessory breast complete with areola and nipple. The presence of a small nipple is the most frequently noted accessory breast structure. In the absence of areola and nipple, the diagnosis is rarely made clinically although there may be a palpable fullness in the area. Fullness may wax and wane with the menstrual cycle or may manifest during pregnancy and lactation. Discomfort, anxiety, pain, restriction of arm movement, milk secretion, and local skin irritation can occur. It is mostly harmless; many affected women desire a plastic surgery operation to remove the additional breasts, for purely aesthetic reasons. Removal of the tissue will relieve the physical discomfort and also confirms the diagnosis. Liposuction is an alternative if this option is feasible.
