Unsuspected non-Hodgkin's lymphoma discovered with routine histopathology after elective total hip arthroplasty

The utility and cost-effectiveness of routine histologic examination of specimens from elective total joint procedures continues to be a source of debate. We describe a case of unsuspected non-Hodgkin's lymphoma discovered after routine histopathologic examination of a femoral head with osteoarthritis. The evidence both for and against routine tissue submission after elective arthroplasty cases is outlined in a review of the literature. By illustrating a neoplasm that would have been missed without routine pathologic examination, this case underscores a need for continued scrutiny of methods to effectively reduce medical costs while maintaining quality of care.
