Figure 5From: Eosinophilic myocarditis mimicking acute coronary syndrome secondary to idiopathic hypereosinophilic syndrome: a case report Endomyocardial biopsy showing the following: (A) Organizing thrombus in small vessels of endocardium (Hematoxylin and Eosin staining, ×20 magnification). (B) Older areas show organized endocardial scar with rare eosinophils and hemosiderin-laden macrophages (Hematoxylin and Eosin staining, ×40 magnification). (C) Close-up of intact and degranulating eosinophils in the interstitial space, without myocyte necrosis (Hematoxylin and Eosin staining, ×40 magnification). (D) A larger cluster of non-degranulated eosinophils (Hematoxylin and Eosin staining, ×40 magnification).Back to article page
