Intractable Pruritus as a Manifestation of Secondary Hyperparathyroidism in Uremia

Abstract
PRURITUS, a common symptom in uremic patients, is usually observed in the absence of visible skin lesions.1 , 2 The underlying cause of the itching in these patients is unknown, but the "toxic" effect of uremia has usually been implicated.
