History
Individuals with chronic renal failure who are afflicted with bullous dermatosis of dialysis typically develop these lesions only after months to years of maintenance dialysis regimens. The lesions are more florid after sunlight exposure; however, patients often are unaware of the role of sunlight in evoking the lesions since they do not note discomfort in the skin during the exposure.
Physical
Vesicles and bullae filled with clear or hemorrhagic fluid and exudative erosions occur chiefly on the dorsal hands, although the scalp, face, and neck also may be affected. Blistering limited to volar fingertips was observed in one case.[9] Healing of crusted erosions leaves atrophic scars. Milia, dyspigmentation, and hypertrichosis occur infrequently.
Causes
The etiology of bullous dermatosis of dialysis remains unclear, although the propensity for sunlight aggravation of the bullae and fragility suggests a phototoxic mechanism.
Because plasma porphyrin levels in individuals with chronic renal failure may be mildly elevated,[10] porphyrin photosensitization might play a contributory role in some cases. However, porphyrin photosensitization is not likely to be the primary cause because many dialysis patients with similarly mild elevations of plasma porphyrin levels do not develop photocutaneous lesions. Speculations that photosensitizers encountered during dialysis (eg, compounds emanating from plastic tubing) are responsible remain unproven. Concomitant use of therapeutic agents with phototoxic potential (eg, furosemide) cannot be identified in most cases. Effects of high aluminum concentrations from therapeutic or environmental sources on enzymes of heme biosynthesis, leading to overproduction of porphyrins, have been suggested as possible etiologies[11] but remain unproven.
