Gigantic giant cell tumor of the anterolateral rib treated with wide resection

Abstract

Giant cell tumors usually arise in the epiphyseal region of the limbs, and their occurrence in the ribs is unusual. We presented a case of a 26-year-old male with a 2 years progressively growing lump on his right anterolateral chest. There was no pain and cardiopulmonary symptoms. Chest radiograph revealed an osteolytic lesion over the right 10th rib with chondroid matrix and a wide transition zone that grew expansively accompanied with the destruction of the 10th rib. Abdominal computed tomography scan confirmed a soft-tissue mass with 15 cm × 11 cm × 10 cm in dimension with the destruction of anterolateral 10th rib. The patient underwent en bloc-wide excision, including the 9th–11th ribs, followed by diaphragm repair and chest wall reconstruction.
