Abstract
Giant cell tumor (GCT) constitutes a relatively common benign bone tumor, characterized by its local aggressiveness. The most frequent site of occurrence is in the axial skeleton (distal femur or proximal tibia). To date, there have been few reports of atypical presentations, such as at the level of the sternum. In this report, we present the case of a 24-year-old female patient who presented with an indurated mass in the sternal region, progressively growing and associated with pain. Radiological findings revealed an osteolytic mass originating from the body of the sternum, involving almost its entire extent and projecting into the soft tissues, reaching the superficial plane. Due to the extent of the disease and the extensive involvement of the sternal body, resection of the body and manubrium of the sternum was performed. The surgical defect was reconstructed with polypropylene mesh, titanium bars, an omental patch and a skin graft, achieving adequate stability of the thoracic cage and favorable cosmetic results.
