title: Giant-cell tumor of the fourth metacarpal bone in children: case report.
abstract: Giant-cell tumor is a rare benign tumor that generally arises in long bones of the lower extremity in adults. The involvement of the metacarpal bone in children is extremely rare. The authors report the case of an 8-year-old boy admitted for a painless swelling of the posterior surface of the fourth right metacarpal bone. The radiological examination showed an expansile osteolytic lesion with a multilocular appearance. Total resection of the metacarpal bone and reconstruction with free fibular graft was performed. We highlight the rarity of this neoplasm in childhood and discuss epidemiological, clinical, radiological, and therapeutical characteristics of this pathology.
