Microscopic honeycombing 
Microscopic honeycombing is a very common finding in UIP. There
is controversy over the origin of this lesion, but it is composed
of normal-appearing bronchiolar epithelium (arrow) lining small
cystic spaces that are typically filled with mucous (m) and acute
inflammatory cells. One hypothesis holds that microscopic honeycombing
is the result of complete alveolar loss in the lobule, with only
the terminal bronchiole and pulmonary artery branch remaining.
