Thrombocytosis due to a bone marrow disorder
A high platelet count can occur in a number of different bone marrow diseases but most especially in the myeloproliferative diseases, chronic myeloid leukaemia, and the myelodysplastic syndromes.
Reactive thrombocytosis.

Thrombotic Thrombocytopenia Purpura or TTP: A disorder of severe thrombocytopenia or abnormally low platelets that can affect multiple organs in the body.
Thrombocytosis is increased platelet count. This may occur in certain disease states such as cancer, chronic infections, and certain blood diseases, and may cause increased blood clot formation.

essential thrombocytosis
An increased number of thrombocytes (platelets) in the blood, without a known cause. Also called essential thrombocythemia.
Definition Thrombocytosis is a blood disorder in which the body produces a surplus of platelets (thrombocytes). Description Thrombocytosis is an abnormally increased number of platelets in the blood.
Essential thrombocytosis: Essential thrombocytosis occurs when the body produces too many platelet cells. These cells help the blood clot in order to stop bleeding.
Also called essential thrombocytosis.

Myelosuppressive therapy may be used for patients with severe symptoms, such as extreme thrombocytosis, a rapidly enlarging spleen, and hypermetabolism. It's also used for elderly patients who have difficulty tolerating the phlebotomy procedure.
The bone marrow and blood show a number of other abnormalities (including maturational arrest of neutrophil precursors at the promyelocyte stage, absolute monocytosis, eosinophilia and thrombocytosis). The gamma globulin level in blood is low.
Hematologic paraneoplastic syndromes: Patients with cancer may develop pure RBC aplasia, anemia of chronic disease, leukocytosis (leukemoid reaction), thrombocytosis, eosinophilia, basophilia, and disseminated intravascular coagulation.

An abnormally high number of red blood cells is called erythrocytosis. An abnormally high number of platelets is called thrombocytosis. An abnormally high number of white blood cells is called leukocytosis.
White blood cell counts greater than 12,000 (leukocytosis) occur in about 60% to 80% of individuals, and platelet counts greater than 400,000 (thrombocytosis) in about 50% to 70%.
Thrombocyte is the medical term for platelet. Thrombocytopenia means a lower platelet count in the blood compared to the normal range. Thrombocytosis refers to a greater number of platelets compared to the normal range.
