Rare Clonal Myeloid Diseases

The “classical” myeloproliferative neoplasms such as essential thrombocythemia (ET), polycythemia vera (PV), primary myelofibrosis (PMF) and chronic myeloid leukemia (CML) are relatively rare disorders. Due to the long life span of most patients with these diseases however, the prevalence is quite high, so that patients with these diseases are commonly seen in hematological outpatient departments.
