Cutaneous ulcerations on hands and heels secondary to long-term hydroxyurea treatment

Hydroxyurea is a chemotherapeutic agent used to treat myeloproliferative disorders and other non-neoplastic conditions. Cutaneous side-effects have been described in long-term therapy with hydroxyurea and include xerosis, hyperpigmentation, skin atrophy, erythema, alopecia, skin tumours and ulceration of the skin, particularly of the legs. We present a 71-year old patient with chronic myelocytic leukemia (CML) who developed extremely painful ulcers on the hands and heels as well as skin tumours while on long-term therapy with hydroxyurea. The ulcers were resistant to therapy but healed three months after discontinuation of hydroxyurea therapy.
