Acute Colitis

Acute Colitis The inflammatory infiltrate consists exclusively of polys, there is no necrosis. The epithelium has changes consistent with regeneration with nuclear enlargement (arrow), nucleoli, and a round nuclear outline as opposed to the flattened nuclei we saw in the normal mucus producing cells. These findings indicate activation of the mechanisms producing acute inflammation but do not allow us to differentiate between varied aetiologies such ASLC produced by Campylobacter, other acute bacterial infection, first episode ED, trauma, toxins etc. This case was culture proven Campylobacter jejune.
