Definition

1. Noun:
   • A type of gangrene: "cold gangrene" is a medical term referring to a specific form of gangrene. It develops when blood flow to a body part is blocked by an arterial obstruction. The affected tissue dies, but unlike other types of gangrene, it remains dry, does not become infected with bacteria, and turns a dark brown or black color.
