Abstract Objective Describe a case of congenital acinar dysplasia and review the literature. Study Design Retrospective chart review and literature search. Results Congenital acinar dysplasia is a rare malformation of growth arrest of the lower respiratory tract resulting in critical respiratory insufficiency at birth. It is a form of pulmonary hypoplasia that is characterized by diffuse maldevelopment and derange- ment of the acinar and alveolar architecture of the lungs, resulting in the complete absence of gas exchanging units. The growth-arrested lung tissue resembles the Keywords pseudoglandular phase of 16 weeks’ gestation. The etiology is unknown. It is diagnosed ► pulmonary hypoplasia by exclusion of all other causes of pulmonary hypoplasia and a summation of clinical, ► respiratory imaging, and histopathologic findings. insufficiency Conclusion There is no cure and clinical treatment is supportive until death of the ► lung maldevelopment infant. We present a case of congenital
