A Three-Step Reconstruction of the Breast in a Patient With Congenital Unilateral Amastia

Amastia refers to a condition where breast tissue, nipples, and areoles are congenitally absent, and it can affect one (unilateral) or both (bilateral) breasts. Congenital amastia is a rare condition with only 34 reported cases in the literature. In this case, we report a 17-year-old female with congenital unilateral amastia of the right breast. She came to our clinic due to a cosmetic view of this defect, which was bothering her, and greatly reducing the overall quality of her life. Our patient's physical examination revealed the absence of right breast, and there was no other obvious physical or anatomical abnormality. The defect was successfully reconstructed in three steps. Firstly, 200 cc adipose tissue was transferred under the skin before inserting the breast implant due to increasing the thickness between the skin and the nipple-areola. Secondly, after four months breast implant was inserted. Finally, the patient's right nipple-areola complex (NAC) was reconstructed with a skate flap.
