Essential thrombocythemia is one of the myeloproliferative neoplasms with a plethora of thrombohemorrhagic complications. To establish a diagnosis of ET, reactive causes trombosigoz thrombocytosis should be absent and other chronic myeloproliferative disorders should be ruled out [ 1 ].


A bone marrow aspirate revealed significant clumping of platelets. 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.

Essential thrombocythemia ET is a BCR-ABL1-negative myeloproliferative disorder characterized by stem cell-derived clonal myeloproliferation leading to thrombocytosis.

Thank you for copying data from http: The presence of the JAK2 VF mutation is associated with a higher haemoglobin and increased risk of thrombosis in essential thrombocythaemia. An analysis of patients. A long-term clinical trial of interferon alpha-therapy in essential thrombocythemia.

A bone marrow aspirate showed hypercellular bone marrow with increased megakaryocytes, and mutational analysis showed the patient to be homozygous for the JAK2 VF mutation.

Hydroxyurea-induced foot ulcer in a case of essential thrombocythaemia. Inplatelet count started rising again and hemoglobin dropped.

Being a rarely encountered side effect of HU, HU-induced ulcers are frequently underdiagnosed, thus delaying their appropriate management. Among its adverse effects are bone marrow depression, megaloblastosis, fatigue, headache, fever, and gastrointestinal symptoms [ 4 ].

First, the thrombocytosis that is associated with ET, coupled to a poorly understood effect of HU on vessel endothelium and platelets, is likely to result in platelet thrombus with subsequent transient occlusion of microvessels [ 3 ]. As a conclusion this report demonstrates the complication of hydroxyurea-induced leg ulcerations and outlines successful management options.
