Résumé
Scleredema is an uncommon condition of unknown etiology that is characterized by dermal mucinosis and mild sclerosis. It is a symmetrical, diffuse, non-pitting induration of the skin commonly associated with an antecedent febrile illness, diabetes mellitus or paraproteinemia.This is the case of an obese, middle-aged adult female with type 2 diabetes mellitus on oral hypoglycemic medication, who presented with an ill-defined, diffuse erythema and non-pitting induration of the skin on the posterior neck and upper back. It has been estimated that as many as 2.5%-14% of diabetic patients have scleredema. This subset of patients may be under-reported as a consequence of subtle onset and under- recognition. Even lithe prognosis of scleredemadiabeticorum is usually benign, it is important that this condition is recognized since it may have systemic involvement that can lead to complications.
