[Changes in pneumocytes in fibrosing alveolitis].
Some unusual changes of proliferating type II pneumocytes were shown by electron microscopy in idiopathic fibrosing alveolitis. New pneumocytes in cubic metaplasia were loosely connected by abundant microvillous processes. These were scarce on the apical surface but numerous on the basis where they are normally lacking. In the absence of basement membrane microvillous processes communicated directly with fibrosed interalveolar septum.
