57.Lung, bronchiectasis, gross

This is another form of obstructive lung disease known as bronchiectasis. Bronchiectasis occurs when there is obstruction or infection with inflammation and destruction of bronchi so that there is permanent dilation.Once the dilated bronchi are present, as seen here grossly in the mid lower portion of the lung, the patient has recurrent infections because of the stasis in these airways. Copius purulent sputum production with cough is typical.
