Myeloproliferative neoplasms (MPN) are relatively rare chronic hematologic malignancies that include the classic Myeloproliferative Neoplasm Disorders:

Philadelphia chromosome-negative        Philadelphia chromosome-positive
   Essential Thrombocythemia (ET)                Chronic Myelogenous Leukemia (CML)
   Myelofibrosis (MF)
   Polycythemia Vera (PV

There are atypical Myeloproliferative Neoplasm Disorders which include molecularly defined PDGFRA-rearranged eosinophilic/mast cell disorders; PDGFRB-rearranged eosinophilic disorders; systemic mastocytosis associated with c-kit mutation; 8p11 Myeloproliferative syndrome; and juvenile myelomonocytic leukemia with recurrent mutations of RAS. MPN also includes the clinicopathologically assigned variants: chronic neutrophilic leukemia; chronic eosinophilic leukemia; hypereosinophillic syndrome, chronic basophilic leukemia, chronic monomyelomonocytic leukemia, systemic mastocytosis; and unclassified myeloproliferative disorder. Chronic myeloid disorders also include myelodysplastic syndrome.

If you or a loved one have been diagnosed with one of these rare disorders,
YOU ARE NOT ALONE, HELP IS JUST A CLICK AWAY.
