83 Introduction to Myeloproliferative Neoplasms (MPNs)

Michelle To and Valentin Villatoro

MPNs are a group of clonal disorders that involve the proliferation and accumulation of one or more myeloid cell lines (erythrocytes, granulocytes, or platelets). These disorders are caused by  genetic mutations in hematopoietic stem cells.1,2

 

MPNs are commonly seen in middle age adults but some may occur during childhood.1

 

The 2008 WHO classification system lists the following disorders under this category:1

Chronic Myelogenous Leukemia (CML)

Polycythemia Vera (PV)

Essential Thrombocytopenia (ET)

Primary Myelofibrosis (PMF)

 

Note: WHO 2008 lists additional disorders under MPNs but only the ones listed above will be discussed in this eBook.
