Myeloproliferative disease
The myeloproliferative diseases are a group of diseases of the bone marrow where excess cells are produced. The delineation from leukemia is artificial, although the myeloproliferative diseases on the whole have a better prognosis than the leukemias.
The myeloproliferative diseases are:
- Chronic myelogenous leukemia (CML)
- Polycythemia vera (PCV)
- Essential thrombocytosis (ET)
- Myelofibrosis (increased connective tissue with decreased room for production of normal blood cells).
All MPDs arise from precursors of the "myeloid" lineage in the bone marrow. The lymphoid lineage may produce similar diseases, the lymphoproliferative disorders (acute lymphoblastic leukemia, lymphomas and chronic lymphocytic leukemia).
