Thrombocytosis

Thrombocytosis (primary throbocythemia) is a myeloproliferative disease, characterized by bleeding tendency and thrombosis. Peripheral blood platelets continue to increase significantly, function is not normal, and bone marrow megakaryocytes proliferate excessively. Because the disease often has repeated bleeding, it is also called hemorrhagic thrombocytosis, the incidence is not high, more common in people over 40 years old. Thrombocytosis can be divided into two categories: primary and secondary. Primary or idiopathic thrombocytosis is a type of myeloproliferative disease. Patients are mostly adults. Children are rare. About 5% of children can develop acute leukemia.
