Abstract

A large mass as a sign of an infection is rare, and it might convince a physician that it had the appearance of a malignancy. The patient in this case visited our clinics after attending several hospitals, with a mass that had the appearance of a malignancy, based on the severe destructive findings observed on plain radiographs. We report the first documented case of a patient with a large mass (12×7×20 cm) and a low-grade infection, which developed at the proximal thigh after a hip arthroplasty. It is important to realize that an infection accompanied by a large mass, can mimic a highly destructive malignant lesion on plain radiographs.
