General and Systemic Histopathology, C601&C602
    Slide 59: Colon with acute ulcerative colitis
    This can be a challenging slide. There are only islands of remaining mucosa, separated by large expanses of ulceration.  Look in the base of the ulcers and right at the edge of the residual mucosa for the best examples. 

    See this slide with the virtual microscope.

    This is a higher power view of the previous slide. It highlights the areas of neovascularity. Pretty much everything applies here as was said about the previous one. Here you can see the newly developing blood vessels a little better, but still the intensity of the mixed inflammatory infiltrate may be hard to read through.
