Fig. 1C. —64-year-old man with Mycobacterium avium-intracellulare complex pulmonary infection. Photograph of gross specimens from left upper lobectomy shows large necrotic cavitary masses (stars).

These gross findings suggest segmental destruction of bronchi forming necrotic cavities or focal cystic bronchiectasis. Scale = centimeters.
