The cutaneous side-effects of hydroxyurea

The cutaneous side-effects of long-term hydroxyurea therapy are not widely known and only rarely reported. We report on a patient who developed widesp read skin changes, including the recently recognized hydroxyurea dermopathy , during long-term treatment with hydroxyurea for polycythaemia rubra vera. The time course of the clinical changes suggests that they result from dir ect toxicity of hydroxyurea on the basal layer of the epidermis and mucosal surfaces. We aim to increase clinical awareness of this problem.
