Tissues that have lost or are rapidly losing their local blood supply are said to be gangrenous. Even in ancient times, people understood that gangrene was a localised form of tissue death. Dry gangrene and wet gangrene are the two most common types. There are many cases of dry gangrene where no infection is present. Bacterial infection is assumed in all cases of wet gangrene. Wet and dry gangrene typically affect the fingers, toes, and other extremities (hands, arms, feet, and legs).
