A newborn baby's hands and feet show mild acrocyanosis.

Definition

Noun: A persistent, painless bluish discoloration (cyanosis) of the hands, feet, and sometimes the face. It is caused by constriction of the small blood vessels in the skin, typically in response to cold temperatures or, less commonly, strong emotion.

Usage

This is a medical term used to describe a specific clinical sign or condition. * It is used as a countable noun (e.g., an acrocyanosis, signs of acrocyanosis). * It is most commonly found in medical descriptions, diagnoses, and literature.
