Scleredema of Buschke: a report of seven cases

Scleredema of Buschke is an uncommon dermatosis characterized by thickened, indurated skin, sometimes with erythema. Histopathology shows thickened dermal collagen with a mild infiltrate of mucin in the deeper dermis. Seven adults with scleredema are presented, four females and three males, and their mean age at diagnosis was 54 years. All had diabetes mellitus for an average of 13 years prior to the onset of scleredema. Complications of diabetes, especially retinopathy (n = 5), neuropathy (n = 4) and peripheral vascular disease (n = 3), were present in five patients. One patient died (cause not established), and another has life-threatening cardiomyopathy. We have no evidence that the scleredema was a significant aetiologic factor in either case, despite published reports of fatalities related to scleredema. Three patients were followed up for more than 1 year and, irrespective of therapy, the scleredema did not resolve in any patient.
