The development of pseudotumor associated with hip prostheses in metal-metal tribology is a rare complication that brings great morbidity, because it generates early loosening of these implants. The objective is to report a case that describes the treatment of pseudotumor alumour lesion and the release of the previous prosthesis, through the arthroplasty review procedure and discuss this unusual complication. It is related to the release of metallic debris and ions by corrosion of the prosthetic joint interface, especially in the metal-metal tribological pair. The patient underwent resection of the lesion, removal of the loose prosthesis and the hip revision arthroplasty procedure, with revision components in trabecular metal. The patient suffered two episodes of prosthetic dislocation in the postoperative period, being treated conservatively, through unscrupulous reduction. After such procedures there was a good evolution of the case, with no further recurrences.
