Bullosis diabeticorum, a rare skin manifestation of diabetes mellitus. Historically, the lesions were termed ‘phlyctenar’, owing to their resemblance to blisters caused by burns. Tense painless blisters appear rapidly, most commonly over the feet. The causes of these bullae are unclear, with multiple pathophysiologies hypothesized. The condition should be managed by a multidisciplinary diabetic foot care team. Treatment includes early surgical debridement and topical negative pressure wound therapy. This allows better management of the high levels of wound exudate and therefore helps restore plantar skin integrity.
