More in Rare Diseases. Essential thrombocythemia (ET) is a rare disorder in which the bone marrow produces too many platelets. ET is part of a category of diseases known as myeloproliferative disorders, a group of disorders characterized by the increased production of a particular type of blood cell. Platelets are the cells responsible for blood clotting which literally stick together at the site of a laceration or injury in order to stop bleeding. 1  In persons with ET, the presence of excessive platelets can be problematic, causing the abnormal formation of clots inside a blood vessel (a condition known as thrombosis).
