Cutaneous alterations in patients with chronic renal failure.

The purpose of this study was to evaluate the prevalence of dermatologic problems among patients with chronic renal failure (CRF) undergoing hemodialysis or peritoneal dialysis. One-hundred and two patients with CRF were examined for the presence of cutaneous alterations. All patients examined had at least one cutaneous lesion. The most prevalent findings were alterations in the cutaneous pigmentation. Of particular interest was an increased prevalence of hyperpigmented macules on the palms and soles. Other manifestations, seen particularly in the hemodialysis group, included the half-and-half nail, pruritus, and keratotic pits of the palms and soles. Infectious processes were more prevalent in the group undergoing peritoneal dialysis. This study showed that all patients with CRF have some type of cutaneous alteration and that the type of dialysis could have some influence upon the incidence of these changes.
