We present a child with interstitial lung disease (ILD) who was diagnosed with desquamative interstitial pneumonitis following CT thorax and open lung biopsy aged 2 years. Subsequently, surfactant protein gene analysis revealed mutations in the ABCA3 gene. This case of ABCA3 deficient ILD describes a stable clinical course over 10 years and highlights the potential benefit of hydroxychloroquine for this condition.
Keywords: ABCA3; hydroxychloroquine; interstitial lung disease; surfactant protein deficiency.
