ABSTRACT
Obinutuzumab is a fully humanized monoclonal antibody against CD20 used in the treatment of chronic lymphocytic leukemia. Fatal cardiovascular events have been described, but only in patients with known cardiovascular records. We report the case of an adult male with a high-risk chronic lymphocytic leukemia who developed subendocardial injury, with no evidence of coronary atherosclerosis, during the first administration of obinutuzumab.
