Thrombocytosis: A high platelet count can be seen in many different conditions, both benign and malignant: iron deficiency anemia, following splenectomy and other types of surgery, in association with cancer, and as a result of a group of bone marrow disorders known as myeloproliferative neoplasms. It is very important that a high platelet count be evaluated promptly by a hematologist.
