Clinical Features,Diagnosis and Treatment Methods of Eosinophilic Granuloma of Bone in Children / 实用儿科临床杂志

ABSTRACT

Objective To study the clinical features,diagnosis and treatment of eosinophilic granuloma of bone(EGB).Methods Twelve cases(8 male and 4 female)of EGB and their medical record,imaging examinations,follow-up data were reviewed,and the lesion sites,symptom and clinical features were analyzed with reference to relative literature.Results Nine unifocal cases were found in the cervical spine(3 cases),the thoracic spine(1 case),the lumber spine(1 case),the femur(1 case),the metacarpal bones(1 case),and the ilium(2 cases).Three multifocal cases were found in the thoracic and lumber spine(1 case),in the femur,the multiple ribs,the skull,the scapula(1 case)and in the skull,the femur,the ilium(1 case).The most common presenting symptom was pain at the lesion site and restricted motion was obviously in the cervical lesion.The case of the thoracic lesions was found neurologic deficit.Osteolytic destruction was found in the radiologic examination in EGB and the periosteal reaction was found in the long bone lesions,and vertebra plana was considered as typical cha-racteristics in the spine lesion.The lesions not in the spine were diagnosed by biopsy,exclusive methods and close following-up were performed in the spine lesions.Two unifocal were healed spontaneously and three were performed with curettage with one bone grafting.Multifocal and the lesions in the spine underwent chemotherapy.All cases were followed up and no recurrence was found.Conclusions EGB is commonly solitary and not seldom in the spine.Topical pain may be chief complaint.Osteolytic image was found in the radiologic examination.Biopsy and exclusive methods combining closely follow-up were used for diagnosis.EGB is self-limited observation,so curettage or chemotherapy can be used in treatment,and prognosis is good.
