郎罕氏细胞组织细胞病(LCH)以组织细胞的特发性异常增殖和肉芽组织形成为特征,可为局部性或系统性。而郎罕氏细胞是该病的特征性病理成份。LCH常见于儿童,其临床和X线表现为繁杂,可能误为良或恶性肿瘤甚至炎症。其病因和病原尚不明了。骨侵犯是最常见的表现。已经述及的三个主要综合征是:嗜酸性肉芽肿,H-S-C病,L-S病。作者拟评估放射性核素骨扫描(RBS)和骨X线摄影(RSS)在儿童LHC确诊和随访时发现骨病变的相对价值。研
Langerhans cell histiocytosis (LCH) is characterized by idiopathic abnormal proliferation of tissue cells and granulation tissue formation and may be localized or systemic. The Langerhans cell is a characteristic pathological component of the disease. LCH common in children, the clinical and X-ray showed complicated, may be misleading as a good or malignant tumor or even inflammation. The etiology and pathogens is unknown. Bone invasion is the most common manifestation. The three major syndromes that have been mentioned are: eosinophilic granulomatosis, H-S-C disease, L-S disease. The authors plan to evaluate the relative value of radionuclide bone scan (RBS) and bone radiography (RSS) in the detection of bone lesions at the time of diagnosis and follow-up of childhood LHC. research
