General and Systemic Histopathology, C601&C602

Here you can see that
most of the lymph node has been replaced by the tumor. Only a small
amount of the uninvolved node remains along one margin. See this slide with the virtual microscope. |

It would be almost impossible to tell just from the histology the source of the primary lesion in this case, but I do expect you to be able to make a good guess. Note the glandular pattern. See if you can tell where the tumor made its first invasion of this node. |
