Adults may experience: • Bonepain; • Cough and shortness of breath; • Fever; • Frequent urination; • Weight loss; and • Rash. ICD-9: 202.5, 277.89 PROGRESSION LCH is relatively more common in children than in adults.[secure.ssa.gov]
Well-localised bonepain is a common presenting symptom, with pain during both activity and rest. Lesions are lytic. Bonepain usually correlates with a radiologically evident lesion but lesions can be painless.[patient.info]

Bonepain due to bone cysts (18%), rash (13%), and polyuria due to central diabetes insipidus (5%) are the most common manifestations of extrapulmonary involvement and occur in up to 15% of patients, rarely being the presenting symptoms of PLCH.[msdmanuals.com]
He was advised to stop smoking and put on inhalers by his GP who then referred this patient to one of the respiratory physician for further workup and management. Figure 1: Diffuse reticular and cystic changes typically sparing costophrenic angles.[chronic-obstructive-pulmonary-disease.imedpub.com]
Diagnosis was suspected when a reticulonodularpattern was detected by conventional X-ray or by computerized tomography of the lungs. Laboratory tests were altered nonspecifically, and lung function was impaired.[ncbi.nlm.nih.gov]
Imaging: His CXR shows a bilateral, predominantly mid- and upper-zone reticulonodularpattern with some small cystic areas in the upper lobes. There is mild bilateral hilar adenopathy.[ucdenver.edu]
Plain radiograph The earliest change is a diffuse bilateral symmetrical reticulonodularpattern with a predilection for the mid and upper zones. The ill-defined nodules range from 1-10 mm in size.[radiopaedia.org]
Abstract The broncho-alveolar lavage from an 18-year-old girl with proven histiocytosis X of the lung has been cocultivated with Staphylococcusaureus.[ncbi.nlm.nih.gov]
