Muscular hyperplasia ("cirrhosis") of the lung and bronchial dilatations as features of chronic diffuse fibrosing alveolitis.

Muscular 'cirrhosis' of the lung was first described by von Buhl in 1872. An occasional case was described afterwards, but the number has increased in recent years. We have found 25 cases published between 1940 and 1964 that have conformed reasonably well to the accepted concept of the condition. Sixteen of these have come from the United States of America, four from Mexico, two from France, and one each from Scandinavia, Canada, and Britain. These cases are summarized in Table They have been published under various titles, the commonest being muscular cirrhosis of the lung, pulmonary muscular hyperplasia, and bronchiolar emphysema.
