Review Question - QID 217745

A 60-year-old male patient with no recent falls or trauma is admitted for functionally limiting mid-back pain and new onset weakness that started when he slipped off a chair while at home. He had several months of persistent back pain before this, but it acutely worsened. Otherwise, he has been in good health. Imaging was obtained in the ED and demonstrated in Figure A with additional imaging demonstrated punched-out lesions in his proximal humerus and posterior ileum. Laboratory studies demonstrated high levels of monoclonal immunoglobulin. He is indicated for biopsy and kyphoplasty. Which patho-histologic image is most likely to be found on biopsy?
