Idiopathic myelofibrosis is a type of chronic myeloproliferative disorders characterized by splenomegaly, a leukoerythroblastic blood picture, teardrop poikilocytosis, in various degrees of bone marrow fibrosis and extramedullary hematopoiesis. In this paper, the biological characters and pathogenesis of idiopathic myelofibrosis such as mutation of tyrosine kinase receptor, mutation of GABA transporter 1, JAK2 mutation and c-MPl mutation, as well as other pathogenesis related with idiopathic myelofibrosis were reviewed.
