General and Systemic Histopathology, C601&C602
|
Things don't look too bad at this power,
but there is a lymphocytic infiltrate throughout the myocardium. See this slide with the virtual microscope. |

The inflammatory infiltrate is seen
diffusely throughout the muscle. As you would guess, it’s mostly lypmphocytes.
Look in the perivascular connective tissue first. You’ll see plenty. Move into
the myocardium once you know what you’re looking at. It’s a good idea to break
out the normal heart slide first to convince yourself there should be no
inflammatory cells at all where we see these. There are likely to be a few PMNs scattered around. These guys are here to clean up the dead and dying cells, and not as part of the actual infiltrate fighting the virus. |
