Bullosis diabeticorum. A report of two cases with a review of the literature.

Bullosis diabeticorum is a rare complication of long-standing diabetes mellitus. Bullous lesions, which appear like burn-induced blisters, occur suddenly without trauma in the feet. These bullae heal spontaneously without scarring; however, recurrence is common. The etiology of bullosis diabeticorum remains unknown. Several theories exist as to causal and contributory factors related to this cutaneous manifestation of diabetes mellitus.
