#angioneurosis
- Angioneurosis — A well-defined dermatological or neurological disorder, characterized by paroxysmal vasomotor disturbances caused by an abnormal excitability of the vegetative nervous system regulating blood vessel caliber. This structural phenomenon manifests clinically through sudden vascular spasms or vasodilations, leading to local changes in skin color and temperature, circumscribed edemas, or ischemic-type pain, as observed in Raynaud's syndrome or Quincke's edema.
