Q83.0: Congenital absence of breast with absent nipple

Congenital absence of breast with absent nipple, classified by ICD-10 code Q83.0, is a rare birth defect where a baby is born without one or both breasts and nipples. While the exact cause is unknown, it's believed to occur during early fetal development, typically without any genetic or environmental known triggers. Signs of this condition are visible at birth and include the absence of the breast and nipple in the affected area. It doesn't usually involve other health problems and it doesn't affect a person's ability to grow or develop otherwise. This condition can be an isolated occurrence, meaning it happens by chance with no clear reason, or it can sometimes be part of a syndrome, which is a group of related health problems occurring together. Infants with this condition often develop normally in all other respects.
