Abstract


An osteoblastoma is an uncommon benign but painful tumor, typically found on the axial skeleton or on long bones in the case of young patients. Some cases of humeral osteoblastomas have been described in literature but not in men older than 30. We report the case of a painless bone tumor on the humerus of a 52-year-old patient. The CT scan shows a 30 mm hypodense lacunar formation, surrounded by thickened cortical bone resembling an osteoid osteoma. The anatomopathological and immunohistological analyses support the thesis of an osteoblastoma. A course of radiological monitoring without surgical resection was adopted. This unusual case introduces the possibility of carrying out a differential diagnosis with an osteosarcoma and raises the question of the treatment that should be adopted.
