Essential thrombocytosis, more commonly referred to as essential thrombocythemia, is a chronic myeloproliferative neoplasm affecting the hematopoietic system and bone marrow It is characterized by the sustained clonal overproduction of mature megakaryocytes leading to elevated circulating platelet counts, typically 450 × 10⁹/L or greater Most cases are driven by acquired somatic mutations that activate the JAK-STAT signaling pathway, predominantly involving the *JAK2*, *CALR*, or *MPL* genes Whi...

It is characterized by the sustained clonal overproduction of mature megakaryocytes leading to elevated circulating platelet counts, typically 450 × 10⁹/L or greater Most cases are driven by acquired somatic mutations that activate the JAK-STAT signaling pathway, predominantly involving the *JAK2*, *CALR*, or *MPL* genes

It is characterized by the sustained clonal overproduction of mature megakaryocytes leading to elevated circulating platelet counts, typically 450 × 10⁹/L or greater While often asymptomatic, affected individuals are at increased risk for arterial or venous thrombosis, microvascular disturbances, bleeding complications, and potential long-term transformation into myelofibrosis or acute leukemia
