A late presenter and long-term survivor of alveolar capillary dysplasia with misalignment of the pulmonary veins

This report demonstrates a late presenter and long-term survivor (38 months old) of alveolar capillary dysplasia with misalignment of the pulmonary veins (ACD/MPV) and with a heterozygous frameshift mutation in FOXF1. The mild phenotype may be due to his residual normal lung tissue as demonstrated in the chest computed tomography (CT) and histopathological findings. Conclusion: We report the longest survivor of ACD/MPV. The mild phenotype is most likely due to the patient's residual normal lung tissue.
