[Scleredema diabeticorum: successful treatment with UVA-1 phototherapy].

Scleredema adultorum is characterized by induration of the skin on the neck, shoulders and upper back caused by increased accumulation of collagen and aminoglycans in the dermis. The induration may progress and lead to pronounced restriction of mobility. Scleredema diabeticorum is one type of scleredema adultorum associated with diabetes mellitus. Multiple therapies have been tried, but most of them have not proven to be consistently effective. We report two cases of scleredema diabeticorum treated successfully with UVA-1- as well as physiotherapy and topical corticosteroids; this approach led to improvement in skin changes and mobility.
