Detailed explanation-1: -Wet gangrene. Wet gangrene may develop after a severe burn, frostbite or injury. It often occurs in people with diabetes who unknowingly injure a toe or foot. Wet gangrene needs to be treated immediately because it spreads quickly and can be deadly.
Detailed explanation-2: -What are the clinical features of diabetic foot ulcer? A diabetic foot ulcer is a skin sore with full thickness skin loss often preceded by a haemorrhagic subepidermal blister. The ulcer typically develops within a callosity on a pressure site, with a circular punched out appearance.
Detailed explanation-3: -In diabetes, there is a problem with insulin, so glucose remains in the bloodstream and builds. It is this high blood sugar (hyperglycemia) that can cause necrosis. Necrosis from diabetes is because of high blood sugar. Hyperglycemia damages nerves and blood vessels and reduces blood flow.
