Fungal infections are also skin conditions to be aware of. According to the ADA, a common fungal infection associated with diabetes is Candida albicans. Candida albicans is a yeast-like fungus capable of creating “itchy rashes of moist, red areas surrounded by tiny blisters and scales.”

Other possible fungal infections include jock itch, athlete's foot, ringworm and vaginal infections that cause itching.

There are also many other skin conditions known to occur with diabetes, including acanthosis nigricans.

According to the ADA, telltale signs of this condition are raised tan or brown areas that appear on the neck, armpits, elbows, knees or groin. This condition is most commonly associated with those who carry excess weight. That said, doctors can recommend creams that may improve the appearance of these spots.

Diabetic dermopathy is another skin condition associated with diabetes.  This condition occurs due to changes in the small blood vessels caused by the disease.

This condition appears in the form of light brown, scaly patches on the front of the legs that may be oval or circular and resemble age spots. The good news is that this condition does not require doctor care.

Yet another condition associated with diabetes is lipoidica diabeticorum (NLD). NLD causes spots similar to diabetic dermopathy; however, these spots are fewer, larger and deeper.

NLD most commonly begins as a dull, red, raised area. Later, it takes on the appearance of a shiny scar with a violet border. Though this condition is rare, it most often occurs in adult women. The ADA says that no treatment is necessary unless sores break open.
