From: SLE strikes the heart! A rare presentation of SLE myocarditis presenting as cardiogenic shock
Histology of endomyocardial biopsy with hematoxylin and eosin stain depicting an abnormal myocardium region with diffuse myofiber degeneration with significant architectural disarray, extensive infiltration of macrophages (CD68 positive) admixed with a few lymphocytes (CD45 immunostaining), neoangiogenesis (black arrows), and perivascular inflammation. Specifically, no granulomas, giant cells, or cytoplasmic vacuolization are visualized here. The spectrum of morphologic findings was highly suggestive of SLE myocarditis
