title: Total hip replacement pseudotumoral osteolysis.
abstract: We report three cases of pseudotumoral lesion secondary to total hip replacement using metal on polyethylene bearings, presenting two distinct macroscopic aspects: (a) classic inflammatory granuloma and, in one case, (b) onset of hematoma associated with gluteal vessel lesions, probably affected by the pseudotumoral process. Diagnosis was radiographic, with CT-scan serving to confirm and, more importantly, to reveal extension and analyze surrounding tissue. Arteriography is needed when the lesion is liquid, and biopsy may be envisaged depending upon the clinical situation. In all three cases, histology was typically that of granulomatous lesions related to wear debris. Once diagnosis could be established, treatment was similar in both presentations, with surgical revision, which should be as early as possible in case of cortical bone involvement, to prevent pathologic fracture.
