 Absent BreastsAmastia or Poland’s Syndrome: A rare condition wherein the normal growth of the breast or nipple does not occur. Absence of the breast frequently does not occur as the only physical problem. Usually it is associated with problems in the development of the chest bone and muscles, like scoliosis and rib deformities. Unilateral amastia (just on one side) is often associated with absence of the pectoral muscles. Bilateral amastia (with absence of both breasts) is associated in 40% of cases with multiple congenital anomalies or birth defects involving other parts of the body as well. Amastia is distinguished from amazia wherein the breast tissue is absent, but the nipple is present. Amazia typically is a result of radiation or surgery. Rarely, the breast may be completely absent. The normal growth of the breast or nipple never takes place and there is no sign whatsoever of the breast tissue, areola or nipple. Injury to the Breast causing deformity: Various kinds of injuries can affect breast development. This may happen surgically or with trauma. If the nipple and breast bud are seriously injured before puberty, the potential adult breast is destroyed as well. Sometimes injuring the skin can limit future breast development. Most commonly this occurs as a result of a severe burn. The resulting scars are so tight that they won’t allow the breast tissue to develop. In the past, some congenital conditions such as hemangiomas “birthmarks” were treated with radiation, which damaged the nipple and breast bud and prevented later growth. Any serious injury to the breast bud can cause this arrested development. Other Congenital Deformities:
