Scleredema diabeticorum successfully treated with ultraviolet A1 phototherapy

Abstract Scleredema diabeticorum is an uncommon condition. It is one of the cutaneous manifestations in diabetes mellitus that mainly occurs in obese middle‐aged men with insulin‐resistant diabetes. This condition is generally recalcitrant to therapy. Various treatments have been tried with inconsistent results. Here, we describe two cases of scleredema diabeticorum with substantial clinical improvement from a course of medium dose (60 J/cm 2 ) ultraviolet A1 radiation therapy.
