comment:

Hemorrhage ( Figure 1image opens in a pop-up window and Figure 2image opens in a pop-up window ) can be due to chemical exposure, trauma, or other damage to blood vessels or due to a chemical that interferes with factors necessary for normal clotting. It may also be a component of acute inflammation.

recommendation:

Hemorrhage should be diagnosed and graded, unless it is secondary to inflammation or ulceration, in which case it should not be diagnosed separately but should be described in the pathology narrative.
