Résumé
Eosinophils are only a small minority of peripheral blood leucocytes and, in normal subjects, most are found in the tissues of the lung and gastrointestinal tract. Peripheral blood eosinophilia is occurred by various causes, allergic diseases, parasite infection, clonal disorder, and drug. Moderate to severe eosinophilia may be caused by the idiopathic hypereosinophilic syndrome (HES), but the commonest cause of eosinophilia worldwide is helminthic infection and, in industrialized nations, atopic disease. Whatever the cause for the eosinophilia, in certain circumstances the eosinophils produce damage to various organs by activation of eosinophils, thrombotic events, release of eosinophil granule contents, and deposition of eosinophil proteins. Clinical manifestations are characterized by thromboembolic events of the involved organ, such as the heart, lungs, or nervous system. To our knowledge, the association between hypereosinophilia and intraabdominal multivessel (portal, splenic and superior mesenteric vein) thrombosis has never previously been reported. Thus, we report a case with portal, splenic and superior mesenteric venous thrombosis simultaneously with disseminated intravascular coagulapathy in the patient with hypereosinophilia.
