Alveolar Capillary Dysplasia with Misalignment of Pulmonary Veins (ACD/MPV): A Case Series

Figure 1

Case report 2: necropsy lung histology (hematoxylin and eosin staining) demonstrates the characteristic histologic features of ACD/MPV: thickened alveolar septae with scarce dilated pulmonary capillaries located away from the alveolar epithelium, with absence of the usual alveolar-capillary barrier ; medial hypertrophy of small pulmonary arteries and muscularization of distal arterioles (▸); congested pulmonary veins malpositioned, adjacent to pulmonary arteries in the same adventitial sheath (*); lymphangiectasis not present.
