Classification and diagnosis of myeloproliferative neoplasms according to the World Health Organization criteria. These extremely painful ulcers, although small and superficial, rarely heal if the medication is not withdrawn [ 3 esanslyel. JAK2 VF mutation is associated with increased risk of thrombosis in Chinese patients with essential thrombocythaemia. Our 3 patients with HU-induced ulcers healed completely after discontinuation of HU.

Meanwhile, the platelet counts were rising.

Two weeks after discontinuing HU, the ulcerations drastically improved. Aging Clin Exp Res. We herein report 3 cases of HU-induced ulcers that were treated by discontinuation of HU and introduction of interferon, with marked improvement of the ulcers and good control of the ET.

High prevalence of arterial thrombosis in JAK2 mutated essential trombowitoz Because it promotes cell death, HU can decrease keratinocyte viability, which in turn will hinder any re-epithelialization after the injury done by the above mechanisms. HU was then stopped and the patient was switched to anagrelide. Increased risk of recurrent thrombosis in patients with essential thrombocythemia carrying the homozygous JAK2 VF mutation. An trobmositoz treatment for ET is hydroxyurea HUyet it is well known to cause several side effects, among them being HU-induced multiple and painful treatment-resistant leg ulcers [ 2 ].


Classification and diagnosis of myeloproliferative neoplasms: J Am Acad Dermatol. Table 1 Classification of ET along with recommended treatment [1]. Vascular events in Korean patients with myeloproliferative neoplasms and their relationship to JAK2 mutation.

Table 1 shows the different risk strata for patients with ET along with their recommended treatment.

Wadleigh M, Tefferi A. This report highlights an important and often undiagnosed toxicity associated with hydroxyurea and its successful management in ET patients.
