''Sternberg's Diagnostic Surgical Pathology'' suggests using the term ''diverticular disease'' instead of trying to distinguish between ''diverticulosis'' and ''diverticulitis'', as ''diverticulitis'' clinically may be seen without objective evidence of inflammation.<ref>{{Ref Sternberg5|1346}}</ref> | |||
*This is reasonable, considering that (1) sampling in large specimens may miss the definite active inflammation, and (2) the distinction is academic, as the management is not driven by this detail of the pathologic findings. | |||

===Biopsy with possible ''diverticular disease-associated colitis''=== | |||
<pre> | |||
The endoscopy report describes diverticular disease. The general differential diagnosis for histologic colitis (infection, inflammatory conditions, ischemia, iatrogenic causes) should be considered. | |||
Inflammation restricted to areas with diverticular disease may be "diverticular disease-associated colitis". Clinical correlation is required. | |||
