Cells. When they break down, scar tissue forms, which over time damages your bone marrow. Patient concerns: The patient was admitted because of abdominal discomfort and enlarged spleen for 19 months. Patients with ET may slowly progress to PV, especially those carrying the Janus kinases (JAK)-2(V617F) mutation. Leukemic evolution of polycythemia vera and essential thrombocythemia: genomic profiles predict time to transformation. It's rare, but polycythemia vera may lead to acute leukemia or myelofibrosis, which are also blood diseases but are more serious.
