1. Neurosis marked by poor digital circulation of the extremities: Angie suffered from acroasphyxia and was so concerned about her fingers and toes being so cold, even when she had socks on.
2. Impaired finger circulation, possibly a mild form of Raynaud’s disease (spasm of the digital arteries causing pallor or blanching of the fingers and toes): Acroasphyxia shows a purplish or waxy white color of the fingers, with subnormal local temperature and paresthesia or abnormal skin sensations.

Acroasphyxia is also known as "dead fingers" or "waxy fingers".
