A rare case of childhood interstitial lung disease attributed to desquamative interstitial pneumonia

Desquamative interstitial pneumonia is a rare form of interstitial lung disease in children that can be idiopathic but is usually associated with an inborn error of surfactant metabolism. We reported DIP in a thirteen-year-old girl who was referred to our outpatient clinic because of worsening dysnoea. High-resolution computed tomography showed ground-glass attenuation with honeycombing and intralobular, interstitial septal thickening suggestive of an interstitial lung disease. Transbronchial lung biopsy was performed and histopathology findings were consistent with desquamative interstitial pneumonia. The patient was started on steroid therapy with oxygen support. Unfortunately, she died a month after being diagnosed due to disease progression.
