Fungal infections of the skin often affect people with diabetes. Types of fungal skin infections include ringworm, jock itch and athlete's foot, according to EverydayHealth.com. These infections generally appear as red, scaly or bumpy patches of skin. Other symptoms include itching, burning and, occasionally, blisters. Jock itch appears in the groin area, while athlete's foot appears between the toes and on the tops and bottoms of the feet.

Granuloma annulare is a rash that causes defined round or arc-shaped bumps on the skin, notes Web MD. The rash occurs most often on the ears and fingers, but in some cases it appears on the chest or abdomen. Some diabetics treat this rash with a topical steroid, such as hydrocortisone.

Cellulitis is an infection that occurs when bacteria, such as Staphylococcus or Streptococcus enter the skin through a cut or scrape, explains Skinsight. Symptoms include redness, swelling and warmth in the infected area. Fever, chills and fatigue sometimes occur as well. The areas most often affected are the legs, feet, arms, hands and face.
