Introduction: Secondary thrombocytosis, also known as reactive thrombocytosis, is defined as an abnormal increase in platelet count as a result of another underlying medical or surgical condition. Once the medical cause of reactive thrombocytosis was determined, it could be treated. In this case, supportive treatment with no iron supplements for anemia and infection improved the case condition rapidly.
