Myeloproliferative neoplasms (MPNs)
Besides leukemia, we have other types of blood alterations associated with the stem cells in the bone marrow. They are known as myeloproliferative neoplasms. They affect the myeloid cell lines, which include red blood cells, white blood cells, and platelets. It is a dysfunction in the bone marrow, and it is subdivided into various types depending on the cell that is being overproduced.
The most important myeloproliferative neoplasms are polycythemia vera, essential thrombocythemia, eosinophilia, and myelofibrosis.
