An increase in blood platelets.
Abnormal increase in the number of platelets. Often causes no symptoms. Usually occurs following removal of the spleen or with hemolytic anemias, hemorrhage or iron deficiency. May also occur in advanced cancer, Hodgkin's disease or other lymphomas. See Anemia, hemolytic; Hodgkin's disease; lymphoma.
A reactive, non-neoplastic over-production of platelets. This situation may accompany a variety of inflammatory conditions and other situations. It is usually transient. It should be distinguished from thrombocythemia, a spontaneous clonal overproduction of platelets that is usually persistent.
A condition in which too many platelets are found in the blood.
increase in the number of platelets in the blood which tends to cause clots to form; associated with many neoplasms and chronic infections and other diseases
The condition of having abnormally high numbers of platelets.
Thrombocytosis is the presence of high platelet counts in the blood, and can be either reactive or primary (also termed essential and caused by a myeloproliferative disease). Although often symptomless (particularly when it is a secondary reaction), it can predispose to thrombosis in some patients.
