What is acrocyanosis in newborns?

• A. Normal bluish discoloration of hands and feet in newborns that decreases over the first few days.
• B. A sign of congenital heart disease.
• C. A normal skin condition that occurs after 6 months.
• D. A disease causing rashes.

Answer: (A)

Acrocyanosis is a normal, temporary bluish color of a newborn’s hands and feet caused by immature peripheral circulation as the infant’s cardiovascular system adapts after birth. It often appears at birth or shortly after and tends to improve within the first few days as blood flow to the extremities increases and the baby stays warm. This is different from central cyanosis, which involves blue color of the lips, tongue, or trunk and can indicate heart or lung problems. If the bluish color in the extremities persists beyond a few days or central areas become involved, further evaluation is needed. The other statements don’t fit because acrocyanosis is not a sign of congenital heart disease, it doesn’t occur after 6 months as a normal finding, and it isn’t a rash or disease.
