Histologic appearance of the lungs demonstrating remodelling of pulmonary venules, foci of pulmonary capillary hemangiomatosis and segmental alveolar capillary congestion. The upper circle surrounds a relatively normal pulmonary venule, where the lower circle surrounds a vein with severe remodelling (intimal fibrosis and complete obstruction of the lumen), the arrows point to areas with segmental alveolar capillary congestion and the arrowheads indicate foci of pulmonary capillary hemangiomatosis adjacent to the remodelled veins. Haematoxylin and eosin, bar = 50 µm
