'''Myelofibrosis with myeloid metaplasia''', also known as '''agnogenic myeloid metaplasia''', '''chronic idiopathic myelofibrosis''', and '''primary myelofibrosis''',<ref>Older terms include "myelofibrosis with myeloid metaplasia" and "agnogenic myeloid metaplasia". The [[World Health Organization]] utilizes the name "chronic idiopathic myelofibrosis", while the International Working Group on Myelofibrosis Research and Treatment calls the disease "primary myelofibrosis".</ref> was first described in 1879 and is currently classified as a [[myeloproliferative disease]] caused by the growth and proliferation of an abnormal [[bone marrow]] stem cell, resulting in the [[fibrosis|replacement of the bone marrow with fibrous connective tissue]]. An eponym for the disease is Heuck-Assmann disease, or Assmann's Disease.

==Presentation==
==[[Myelofibrosis epidemiology and demographics|Epidemiology and Demographics]]==
The [[bone marrow]] is replaced by collagen fibrosis, impairing the patient's ability to generate new blood cells resulting in a progressive anemia. It is usually reactive following other [[myeloproliferative disorders]], such as [[polycythemia rubra vera]] or [[essential thrombocytosis]]. Extramedullary hematopoeisis occurs as the haemopoetic cells migrate away from the bone marrow, to the liver and spleen. Patients often have [[hepatosplenomegaly]] and [[poikilocytosis]]. The mean survival is 5 years and causes of death include infection, bleeding, organ failure, portal hypertension, and leukemic transformation.


==Diagnosis==
==[[Myelofibrosis risk factors|Risk Factors]]==
Diagnosis is based upon:
# Normochromic normocytic anaemia
# Red cell poikilocytosis on blood film (tear drop RBCs)
# JAK 2 mutation on Val 617 Phe locus in 50%
# Raised lactate dehydrogenase
# Raised neutrophil alkaline phosphatase score
# Bone marrow biopsy may show increased cellularity and fibrosis
