Tuberous Breast Deformity

Tuberous Breast Deformity, also known as Constricted Breast Deformity, occurs when the lower pole of a breast does not fully develop. There is great variablity in how it presents, but in general the lower pole of the breast is short and underdeveloped with a lower breast fold that is higher than normal. As a result, as the breast develops it herniates  through a fibrous band internally which leads to a small, sometimes pendulous breast with an abnormally large areola. From what you describe, you may very well have some form of this deformity.
