Key Points
* Blister-like lesions associated with diabetes
* Rare
* Heal on their own

Diabetic bullae are blister-like lesions that affect those who have diabetes. The lesions occur spontaneously on the feet and hands and can range from half a centimeter to 17 centimeters long. Diabetic bullae is rare, but appears more often in those who have had diabetes for a longer period of time or who have experienced complications due to diabetes.

There are two types of Diabetic bullae: 1) Intraepidermal bullae, characterized by blisters that are filled with a clear, sterile viscous fluid. These blisters generally heal on their own in two to five weeks without scarring. 2) Subepidermal bullae, characterized by blisters filled with blood. Scarring and atrophy may occur after healing.

Treatment

In most cases, Diabetic bullae will heal on its own. However, it is advised that you do not break the blisters, as it can lead to secondary infection.
