Hematopathology

Hemolytic anemia or haemolytic anaemia is a form of anemia due to hemolysis, the abnormal breakdown of red blood cells (RBCs), either in the blood vessels (intravascular hemolysis) or elsewhere in the human body (extravascular).

Macrocytosis is the enlargement of red blood cells with near-constant hemoglobin concentration, and is defined by a mean corpuscular volume (MCV) of greater than 100 femtolitres (the precise criterion varies between laboratories).

Leukocytosis is white cells (the leukocyte count) above the normal range in the blood.

Polycythemia (or Polycythaemia, see spelling differences) vera (PV) (also known as erythremia, primary polycythemia, Vaquez disease, Osler-Vaquez disease and polycythemia rubra vera) is a neoplasm in which the bone marrow makes too many red blood cells.

Polycythemia (also known as polycythaemia or polyglobulia) is a disease state in which the proportion of blood volume that is occupied by red blood cells increases.

Megaloblastic anemia (or megaloblastic anaemia) is an anemia (of macrocytic classification) that results from inhibition of DNA synthesis during red blood cell production.

Pancytopenia is a medical condition in which there is a reduction in the number of red and white blood cells, as well as platelets.

Thrombocytopenia refer to a disorder in which there is a relative decrease of thrombocytes, commonly known as platelets, present in the blood.

Warm Antibody Autoimmune Hemolytic Anemia (WAIHA) is the most common of the autoimmune hemolytic diseases.

Aplastic anemia is a rare disease in which the bone marrow and the hematopoietic stem cells that reside there are damaged.

Acute myeloblastic leukemia is a form of myeloid leukemia affecting myeloblasts.

A splenic tumor is a rare form of tumor that may be malignant or benign.

Progressive transformation of germinal centres, abbreviated PTGCs and also progressive transformation of germinal centers, is a reactive lymph node process of undetermined etiology.
