Probe-based confocal laser endomicroscopy in diagnosis of desquamative interstitial pneumonia in nonsmoker.

Desquamative interstitial pneumonia is a rare disease that is predominantly associated with smoking. Surgical biopsy is usually recommended for the diagnosis of this disorder. Probe-based confocal laser endomicroscopy (pCLE) is a new method of minimally invasive in vivo microscopic image of airways and alveoli.
