Explanation:

Gangrene is the death of body tissue due to insufficient blood supply in a particular region or bacterial infection. The disease is most common in the extremities of the body, including feet, toes, arms and legs, but can also occur in muscles and internal organs.

There are two types of gagrena, dry and moist. Moist gangrene refers to gangrene tissue where there is bacterial infection. Swelling, sores with no demarcation line, unpleasant odor, blisters and "wet" appearance are common in cases of wet gangrene. It usually develops after severe burns, frostbite, or injury. It also often occurs when people with diabetes have foot or toe sores. Moist gangrene should be treated immediately as it spreads quickly and can be fatal.

The symptoms presented by the patient, exposed in the question, show that they are experiencing a case of moist gangrene.
