| polycythaemia | <haematology> Increase in the haemoglobin content of the blood, either because of a reduction in plasma volume or an increase in red cell numbers. The latter may be a result of abnormal proliferation of red cell precursors (polycythaemia vera, Vaquez Osler disease). Origin: Gr. Haima = blood (18 Nov 1997) |

| polycythaemia rubra vera | <haematology> A condition characterised by enlargement of the spleen and the increased production of red blood cells by the bone marrow. Diagnosis is based on an increased number and volume of red cells. The total number of white blood cells and platelets may also be increased. Treatment will vary according to the age of the patient and severity of the disease. This condition carries an increased risk of developing acute leukaemia. The disease usually begins in late middle life and is slightly more common in males. (11 Nov 1997) |

| polycythemia | The opposite of anaemia. Too many red blood cells. Polycythemia formally exists when the haemoglobin, red blood cell count, and total rbc volume are all above normal. (12 Dec 1998) |
| polycythemia hypertonica | Polycythemia associated with hypertension, but without splenomegaly. Synonym: Gaisbock's syndrome. (05 Mar 2000) |
| polycythemia rubra | Overproduction (proliferation) of red blood cells due to bone marrow disease (myeloproferative disorder). Pv tends to evolve into acute leukaemia or a condition with the marrow replaced by scar tissue (myelofibrosis) (12 Dec 1998) |

| polycythemia vera |
A disease in which there are too many red blood cells in the bone marrow and blood, causing the blood to thicken. The number of white blood cells and platelets may also increase. The extra blood cells may collect in the spleen and cause it to become enlarged. They may also cause bleeding problems and make clots form in blood vessels.

| polycythemia vera |
A clonal disease characterized by the over-production of blood cells by a mutant multipotential hematopoietic stem cell in the marrow. The hallmark of the disease is an increased number of red cells. The number of white blood cells and platelets are also usually increased. The accumulation of red cells is progressive and usually requires treatment at the time of diagnosis. ...
