Transmural lesions are characterized by their ability to penetrate through the entire wall of an organ or structure. This means that they extend beyond just the surface layers, affecting all layers of tissue involved, from the outermost to the innermost.

In the context of various medical conditions, transmural lesions can significantly impact the function and integrity of organs, especially in cases like inflammatory bowel disease, where the inflammation can affect the entire thickness of the bowel wall, leading to serious complications. Understanding this depth of penetration helps in determining the severity of a condition and the appropriate treatment strategies.

The focus on full-thickness involvement highlights the importance of addressing these lesions in clinical practice, as they may require more intensive intervention compared to superficial lesions that are limited to the outer layers or surface tissue.
