Diagnosis of Waldenstrom Macroglobulinemia Using Postoperative Histopathology During Routine Total Knee Arthroplasty: A Case Report.

ABSTRACT

CASE We present a 63-year-old patient diagnosed with Waldenstrom macroglobulinemia (WM) through histopathology of bone tissue after total knee arthroplasty for routine osteoarthritis. The patient, surgical team, and the pathologist were unaware of this diagnosis before the surgery. CONCLUSION: The cost-effectiveness of routine histopathologic examination of bone cuts and synovial samples after total joint arthroplasty continues to be a source of debate. Our case highlights an example of the utility of histopathology because it led to the early detection of WM, resulting in prompt treatment to improve quality of life.
