Which statement best describes the lesions associated with Crohn's disease?

The lesions associated with Crohn's disease are best described as asymmetrical and patchy. This characteristic means that the inflammation and damage do not occur uniformly but rather in distinct regions that can be separated by healthy tissue. Crohn's disease tends to affect different segments of the gastrointestinal tract in an intermittent fashion, leading to areas of inflammation (lesions) that are often "skipped," making it appear that there are gaps of normal tissue amidst the inflamed areas.

In contrast to continuous involvement in other conditions, such as ulcerative colitis, where lesions are uniform and contiguous, the patchy inflammatory pattern in Crohn's disease reflects its potential to affect any part of the GI tract—from the mouth to the anus—while also preserving segments of healthy intestinal tissue. This distinct characteristic is crucial in diagnosing and understanding the pathology of Crohn's, as well as guiding treatment approaches effectively.
