acrocyanosis
Pronunciation: ak-roh-sahy-uh-noh-sis
Bluish discoloration of the hands and feet in newborns, typically benign and self-resolving.
Full Definition
Acrocyanosis refers to a bluish or purplish discoloration of the extremities, particularly the hands and feet, commonly observed in newborns during the first few days of life. This condition is generally considered benign and results from immature circulation and peripheral vasoconstriction. It typically resolves spontaneously as the infant's circulatory system matures. Editorial contexts should distinguish this from central cyanosis, which involves the lips and mucous membranes and indicates more serious cardiopulmonary issues.
Usage
Usage note: Should not be hyphenated; distinguish carefully from central cyanosis in medical documentation.
