  Fig. 1 Computed tomography and coronary angiography. A: Initial chest computed tomography showed a large, infiltrative, and heterogeneously soft tissue mass at the left axilla (white arrow). There was no definite mass in the left atrium (black arrow). B: Coronary angiography showed the total occlusion of the distal left anterior descending artery (white arrow). C: The aspirated tissue material appeared as mucoid and whitish debris. D: The final coronary angiography showed that flow had been completely restored (black arrow).

• 

  Fig. 2 Echocardiography. A: Echocardiography showed a huge mass with heterogeneous echogenicity in the left atrium affecting through the mitral valve leaflet before six months ago, at the time of pembrolizumab treatment (white arrow). B: The left atrium tumor mass was significantly decreased at the time of admission in the echocardiography (white arrow head).

  Fig. 3 Pathology findings. A: The primary axillary tumor was cytologically compatible with undifferentiated pleomorphic sarcoma that focally showed discohesive and relatively monotonous round cell components (black arrows) (H&E, × 200). B: The coronary embolus tissues showed similar round cell morphology and a few scattered pleomorphic giant cells (H&E, × 400). C: The tumor cells were diffusely immunoreactive with vimentin, a representative mesenchymal marker (ABC, × 200). H&E: hematoxylin and eosin.
