Figure 1 Apical 4-chamber view obtained by 2-dimensional echocardiography. White arrows mark the borders of the epicardial tumor masses infiltrating the lateral wall of the right ventricle and the right atrium. LA = left atrium; LV = left ventricle; RA = right atrium; RV = right ventricle. The American Journal of Medicine 2016 129, e117-e120DOI: (10.1016/j.amjmed.2016.03.028) Copyright © 2016 Elsevier Inc.

Figure 3 Macroscopic view of the left ventricle, showing the infiltrated myocardium and endocardium. The American Journal of Medicine 2016 129, e117-e120DOI: (10.1016/j.amjmed.2016.03.028) Copyright © 2016 Elsevier Inc. Terms and Conditions
Figure 4 Morphology and immunohistochemistry. (A) Infiltration of the myocardium by atypical large cells with a high nuclear/cytoplasmic (hematoxylin and eosin; original magnification ×200). (B) Myeloperoxidase (×400), (C) Chloracetate esterase stain (×400) highlight the myeloid differentiation of the blasts, and (D) CD68–KP1 (×400) shows a variable expression.
