My daughter was born with only her right breast (nipple and breast tissue). Her left side is completely lacking in both nipple and breast tissue and presents as normal skin. Her pectoral muscles are intact. This condition is known as Amastia and is extremely rare. To my knowledge the cause is unknown. Definition of Amastia: A rare condition wherein the normal growth of the breast or nipple does not occur. Unilateral amastia (just on one side) can also, but not always, be associated with absence of the pectoral muscles. Bilateral amastia (with absence of both breasts) is associated in 40% of cases with multiple congenital anomalies (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 is typically a result of radiation or surgery, but it is possible for it to be congenital as well.
Achromasia is the absence of normal skin pigmentation, or the inability of a cell or tissue to be stained.
