The function is also abnormal, 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. The main pathophysiological characteristics are: clonality, reactivity or secondary, familial or hereditary. Treatment remains to be resolved.
