White blood cells and platelets are additionally misshapen and immature. In primary myelofibrosis there are often low ranges of circulating red blood cells, a situation known as anemia. Most patients with myelofibrosis have an enlarged spleen, and in some cases, an enlarged liver. Symptoms of myelofibrosis can include fatigue, shortness of breath, belly discomfort, pain beneath the ribs, feeling full, muscle and bone pain, itching, and night sweats. Myelofibrosis and Myelodysplastic Syndrome Symptoms This secondary myelofibrosis can also be known as post-polycythemia vera (PPV) or post-essential thrombocythemia (PET-MF). Primary myelofibrosis (also known as chronic idiopathic myelofibrosis) is myelofibrosis that has been diagnosed without any prior MPN’s, while secondary myelofibrosis is myelofibrosis that has developed after the patient has first been diagnosed with essential thrombocythemia (ET) or Polycythemia Vera (VR). Primary Myelofibrosis and Secondary Myelofibrosis

Myelofibrosis can affect anyone however, it is most frequently diagnosed in people older than 50. Affected people may stay symptom-free for many years, and then develop the florid disease. The symptoms associated with primary myelofibrosis differ and are associated to a build of abnormal blood cells and fibers in the bone marrow. Myelofibrosis is part of a group of diseases called myeloproliferative disorders/neoplasms (MPN), and are characterized for abnormal cells which sometimes harbor mutations in the JAK pathway. Myelofibrosis (MF) is rare disorder in which abnormal blood cells and fibers build up in the bone marrow. In about 1 in 3 patients, MDS can progress to a quickly growing cancer of bone marrow cells called acute myeloid leukemia. The World Health Organization divides myelodysplastic syndromes into subtypes based on the kind of blood cells - red cells, white cells and platelets - involved.

Overall, MDS is relatively uncommon, with an incidence of between four to five people per a population of 100.

People with MDS have low numbers of red blood cells (anemia), and the cells may have a mutation in their DNA. The Myelodysplastic Syndrome (MDS) is a term for a group of frequent malignant stem cell diseases, mainly encountered in older individuals. Myelofibrosis and Myelodysplastic Syndrome, like low blood counts can be treated with blood transfusions, where red blood cells or platelets are replaced.
