Clinical Features of Diabetic Bullae (Bullosis Diabeticorum)

Has the patient had the sudden appearance of one or more tense blisters or bullae?

Are the bullae on an acral region (finger, hand, forearm, toe, foot, lower leg)?

Are the lesions symptomatic (other than for the swelling)?

Are the bullae full of clear fluid?

Do the bullae resolve in a few weeks without scarring?

Are the bullae intraepidermal or subepidermal?

Is there another disorder that can explain the bullae better?
