Here the authors present the case of a 2-y-old girl who was diagnosed with isolated pulmonary Langerhans cell histiocytosis by histopathology; a lung biopsy sample was obtained using a cryoprobe via a flexible bronchoscope. The girl was brought in with complaints of loss of weight, appetite loss, and rapid breathing for the past 2 mo. Examination revealed hypoxia, tachypnea, clubbing with failure to thrive, and bilateral crepitations on auscultation. Imaging studies showed ground-glass opacities with multiple cystic lesions in both lungs. A preliminary diagnosis of LCH was made, and transbronchial cryobiopsy was done via a flexible bronchoscope. Histopathology confirmed the diagnosis with Cluster of differentiation 1a (CD1a) staining. A flexible bronchoscope can be a useful tool for obtaining lung biopsy samples using a cryoprobe in children.
