Việc chẩn đoán một khối u xương ở trẻ em có thể trở thành một nguồn của sự lo lắng lớn cho bệnh nhân, các phụ huynh, và các bác sĩ Điều trị. May mắn thay, khối u xương ở trẻ em MOST là lành tính. | Benign Bone Tumors of Childhood Albert J. Aboulafia MD Robert E. Kennon MD and James S. Jelinek MD Abstract The diagnosis of a bone tumor in a child can be a source of great anxiety for the patient the parents and the treating physician. Fortunately most bone tumors in children are benign. Although there are a variety of benign bone tumors that affect skeletally immature patients most have such characteristic clinical and radiographic presentations that the diagnosis can be made with reasonable accuracy without a biopsy. However some benign bone tumors can simulate a malignant process and may be best handled by referral to a person trained in orthopaedic oncology for additional evaluation. Treatment alternatives are in part related to the Musculoskeletal Tumor Society stage of the lesion. Recurrences of certain lesions such as aneurysmal bone cysts and osteoblastomas can be problematic. By becoming familiar with the presentation of the more common benign bone tumors in children physicians will be able to alleviate fears establish a diagnosis and make treatment recommendations in the most effective manner. J Am Acad Orthop Surg 1999 7 377-388 The true incidence of benign bone tumors in children is unknown. Much of the data regarding the incidence of benign bone tumors is based on material from series of biopsied or treated lesions. Furthermore many benign bone tumors in children are diagnosed radiographically and never require further treatment. It is estimated that the incidence of fibrous cortical defects in children is between 30 and 40 . Because of their characteristic radiographic appearance and relatively predictable clinical course nonossifying fibromas represent only 2 of biopsy-analyzed benign Codman 2 who was the first to recognize the rarity of bone tumors established the registry concept of tumor studies similar series that followed formed the basis on which tumor incidence has been As a group benign bone tumors in children represent
