Low M, Lasley K, Singh P. Atypical case of pulmonary Langerhans cell histiocytosis presenting as miliary nodules. Case Rep Int 2022;11:100106Z06ML2022.ABSTRACT
Pulmonary Langerhans cell histiocytosis (PLCH) is a rare smoking-related interstitial lung disease affecting primarily young adult smokers. Diagnosis is made with typical radiographic findings of centrilobular nodules and cystic lesions on high resolution computed tomography (HRCT) confirmed with tissue biopsy. We describe a case of a 59-year-old man presenting with chronic tobacco use and cough who was found to have an atypical radiographic finding of miliary nodules on HRCT that was confirmed as PLCH on transbronchial lung biopsy.
Keywords: Interstitial lung disease, Miliary nodules, Pulmonary Langerhans cell histiocytosis, Smoking
