Acrocyanosis refers to cyanosis in which area?

Explanation:
Acrocyanosis is the blue discoloration that appears in the extremities—the hands and feet—due to reduced peripheral blood flow, while central tissues such as the trunk and face remain well oxygenated. In newborns, this peripheral cyanosis is common and can be influenced by vasomotor tone and cold stress, often resolving as circulation improves. If cyanosis involves the lips, tongue, or trunk, that would indicate central cyanosis and suggests a more significant issue with oxygenation that warrants urgent evaluation. So, the hands and feet are the area described by acrocyanosis.
