Deficiency in erythrocytes or haemoglobin.
iron-deficiency anaemia
It is caused by a lack of iron, which is required for haemoglobin production.
aplastic anaemia
Failure of blood cell production due to aplasis (absence of development, formation) of bone marrow cells.
haemolytic anaemia
Reduction in red cells due to excessive destruction.
pernicious anaemia
Lack of mature erythrocytes owing to inability to absorb vitamin B12 into the body. (Pernicious mean ruinous or hurtful.)
sickle cell anaemia
A hereditary condition characterised by abnormal shape of erythrocytes and by haemolysis.
An inherited defect in the ability to produce haemoglobin, usually seem in persons of Mediterranean (thalassa is a Greek word meaning sea) background.
Excessive deposits of iron throughout the body.
polycthaemia vera
General increase in red blood cells (erythraemia).
Excessive bleeding caused by a congenital (hereditary) lack of one of the protein substances (factor VIII) necessary for blood clotting.
Multiple pinpoint haemorrhages and accumulation of blood under the skin.
An increase in cancerous white blood cells.
acute myelogenous (myelocytic) (myeloid) leukaemia (AML)
Immature granulocytes (myeloblasts) predominate. Platelets and erythrocytes are diminished because of infiltration and replacement of the bone marrow by large numbers of myeloblasts.
acute lymphocytic (lymphoid) leukaemia (ALL)
Immature lymphocytes (lymphoblasts) predominate. This form is seem most often in children and adolescents; onset is sudden.
chronic myelogenous (myelocytic) (myeloid) leukaemia (CML)
Both mature and immature granulocytes are present in the marrow and bloodstream. This is a slowly progressive illness with which patients may live for many years without encountering life-threatening problems.
chronic lymphocytic (lymphoid) leukaemia (CLL)
Abnormal numbers of relatively mature lymphocytes predominate in the marrow, lymph nodes and spleen. This form of leukaemia usually occurs in the elderly and follows a slowly progressive course.
Abnormal increase in granulocytes in the blood.
An infectious disease evidenced by increased numbers of lymphocytes and enlarged cervical lymph nodes. Also called glandular fever.
muliple myeloma
Maliganant tumour of bone marrow.
