ABSTRACT
We herein reported a case of Langerhans cell histiocytosis (LCH), which was diagnosed by echo-guided bone biopsy and improved without any treatment other than cessation of smoking. A 25-year-old woman, who was a current smoker, presented at our hospital with chief complaints of cough and left back pain. Her chest computed tomography (CT) revealed osteolytic lesion in the 9th rib, a few cysts with ground-glass opacities, and small nodules in the bilateral upper lobes. A biopsy was performed on the bony lesion via echo guide, which indicated the diagnosis of LCH. Lung lesions were consistent with the CT image of LCH. The lytic bone lesion was completely cured after 4 months of biopsy with cessation of smoking and observation.
