  Myelofibrosis
Myelofibrosis is a rare disease of the bone marrow in which collagen builds up fibrous scar tissue inside the marrow cavity.
Myelofibrosis occurs with equal frequency in women and men, but in children it affects girls twice as often as it does boys.
Myelofibrosis is caused by an abnormality in a single stem cell, which causes it to grow out of control.

 Myelofibrosis
Myelofibrosis (also called agnogenic myeloid metaplasia) is a myeloproliferative disorder in which the bone marrow is initially over-active but then develops scar tissue (fibrosis).
The term idiopathic means without known cause and differentiates this form of myelofibrosis from secondary myelofibrosis which may complicate other bone marrow diseases.
In myelofibrosis this network is coarsened and thickened so that normal blood cell production is progressively reduced.

  Myelofibrosis: Myeloproliferative Disorders: Merck Manual Home Edition
Myelofibrosis is a disorder in which fibrous tissue replaces the blood-producing cells in the bone marrow, resulting in abnormally shaped red blood cells, anemia, and an enlarged spleen.
As myelofibrosis progresses, the number of white blood cells may increase or decrease, and the number of platelets typically decreases.
Myelofibrosis may develop on its own (in which case it is also called idiopathic myelofibrosis or agnogenic myeloid metaplasia) or may accompany other blood disorders, such as chronic myelocytic leukemia, polycythemia vera, thrombocythemia, multiple myeloma, lymphoma, and myelodysplasia; tuberculosis; or bone infections.

Symptoms of idiopathic myelofibrosis may include abnormally low levels of circulating red blood cells (anemia), an abnormally large spleen (splenomegaly), an abnormally large liver (hepatomegaly), weight loss, weakness and fatigue due to replacement of normal bone marrow cells, and/or episodes of severe pain in the abdomen, bones, and joints.
Myelofibrosis may be a connective tissue reaction to several types of injury resulting in bone marrow tissue death.

 MF-FAQ myelofibrosis
In the setting of a myeloproliferative disorder, myelofibrosis is accompanied by varying degrees of myeloid metaplasia (often seen as enlargement of spleen and/or liver), due to reactivation of fetal hematopoietic sites than are normally dormant in adult life.
It is this combination that distinguishes myeloproliferative disease-related myelofibrosis from the secondary or interactive myelofibrosis that occurs in the setting of malignancy, chemical or physical injury, infection or infarction.
Patients with idiopathic myelofibrosis who tend to do very well include those whose presenting hemoglobin levels are greater than 10 gm/dl, platelet counts greater than 100x3/ul and only modest enlargement of the liver.

 Benzene Causes Myelofibrosis & Myeloid Metaplasia :.: Metzger Law Group, California Benzene Lawyers   (Site not responding. Last check: )
In 1995, Tondel reported a case of myelofibrosis in a 46-year-old man who had worked as a gas station attendant for 17 years and was exposed to benzene from fueling cars with gasoline and diesel and from inspecting the level of gasoline in arriving tanker trucks.
A proportionate mortality ratio for myelofibrosis was not reported, probably due to an absence of data regarding incidence of the disease in the general population.
Numerous case reports of benzene-induced myelofibrosis have been documented in the medical literature, and the causal association between exposure to benzene and myelofibrosis is supported by the available epidemiologic literature.
