✦ Synopsis

Thrombocytosis is the cause of various complications in myeloproliferative disorders. We present the case of a 54-year-old woman with chronic myelogenous leukaemia who developed large ulcers on both lower legs that were refractory to standard treatment. As concomitant thrombocytosis persisted despite treatment with hydroxyurea, the new megakaryocyte inhibitor anagrelide (Agrelin) was administered and led to normalization of the platelet count within 11 days. The leg ulcers started to heal after 2 weeks and disappeared over a period of 5 months. Our findings argue for a pathogenic role of platelets in the development of leg ulcers in patients with thrombocytosis due to a myeloproliferative disorder.
