Malignant Fibrous Histiocytoma at the Site of an Alumina-on-Alumina-Bearing Total Hip Arthroplasty Mimicking Infected Trochanteric Bursitis

Abstract 

Although the incidence of malignant tumors in patients undergoing total hip arthroplasties (THAs) is known to be lower than the general population, there exist several reports on the development of malignant tumors at the site of THAs. We report another case of malignant fibrous histiocytoma at the site of a THA, which was developed in an older patient who presented a cystic mass around the total hip prosthesis using a ceramic-on-ceramic bearing system, even without evidence of osteolysis or loosening of implants. This is the second case associated with an aluminum oxide prosthesis in English literature.

Keywords: malignant fibrous histiocytoma, total hip arthroplasty, tumor, aluminum oxide
