Idiopathic Hypereosinophilia and Venous Thromboembolism: Is There a Pathophysiological or Clinical Link? Description of an Intriguing Clinical Case

Abstract

Thrombosis events usually occur after prolonged bedrest, pregnancy, hormonal therapy, recent surgery and in the presence of inherited or acquired thrombophilia. However, several other diseases are often associated with thrombosis although their frequency is not easily estimated. Eosinophilia is one of these conditions. From a clinical viewpoint it is very difficult to understand which conditions might lead to a thrombotic event because the underlying pathophysiological mechanisms are different. Here, we report a case of idiopathic hypereosinophilia associated to venous thromboembolism without any other associated prothrombotic condition.
