Bullous dermatosis of hemodialysis.

Bullous dermatosis of hemodialysis (BDH), first described in 1975, is characterized by porphyrialike blisters on sun-exposed parts of the scalp, face, arms, and hands. Four patients with BDH are presented. In two of these patients the deliberate lowering of their serum iron levels led to improvement of the condition. Further investigation into the role of iron metabolism in BDH is suggested.
