The slid above shows my form of Hodgkin's. It is called nodular sclerosis lymphoma. This slide has been dyed to show the difference between the nuclide material (cell nucleus) and scarring. The pink is the scarring, the purple is basically areas where there is DNA material. It is called nodular because if you look you can see little nodes, circles of purple, these are the cancer cells. All of the pink is the sclerosis, or the scarring.
Although there are many types of non-Hodgkin's lymphoma this is a slide of follicular lymphoma. If you notice in this slide there is much less pink (scarring) and much more purple (DNA material). This means, in general terms, there is more cancer cells in the slide. I would guess that is a good thing?
When they are trying to make a diagnosis of Hodgkin's they will look for Reed-Sternberg cells. These cells are what lets them know that is Hodgkin's for sure. They are also called owl eyes.
The two slides above are examples of Reed-Sternberg cells. In both of them, towards the center, you can see where two purple cells appear to be joined, they look kind of like eyes. These are them. If you notice, they are a little bigger than the others.
