Essential thrombocythemia presenting as digital ischemia

Abstract

Essential thrombocythemia is a myeloproliferative disease and is characterized by increased production of platelet and increased megakaryocytes in the bone marrow. Though platelets are high in number but may not function normally and can cause hyperviscosity syndrome and blockage of the blood vessels and other complications. Here, we report two cases of essential thrombocythemia, presented with pain in hands and feet and one with digital infarction. Both the patients had headache and vertigo.
