From: A rare inflammatory myofibroblastic tumor appearing both inside and outside the heart
HE staining (A and B) and CD68 staining (C) of the tumorous tissue confirm the diagnosis of inflammatory myofibroblastic tumor, scale bar = 20 μm. The red-stained long strip-shaped indicated cardiomyocytes, blue-stained spindle-shaped indicated myofibroblasts, other blue-stained cells indicated plasma cells or macrophages. Echocardiography 8 months post-operatively (D) shows no hemodynamic abnormality
