A Case of Follicular Bronchiolitis as the Histological Counterpart to Nodular Opacities in Bronchiectatic Mycobacterium avium Complex Disease

Here we report the case of a 72-year-old woman with nodular bronchiectatic Mycobacterium avium complex (MAC) disease. Chest computed tomography on admission revealed multiple micronodular and branching opacities in both lobes with segmental distribution; bronchiectasis and bronchial wall thickening...
