What are tumor cells monoclonal kappa light chain positive?

These are tumor cells that arose from a single lymphocyte or plasma cell. The kappa light chain is a piece of the structure of an antibody; monoclonal means "single type". Therefore, these are tumor cells that all produce the same antibody structure, which indicates they are all derived from a single tumor cell that originally made this antibody structure.

What does it mean to have a Well-differentiated hepatocellular liver tumor?

It means that the hepatic tumor cells closely resemble the real and "healthy" hepatic cells. When talking of tumors, the term "well-differentiated" is a "good" indicator. Cells "differentiate" one from the others in order to accomplish their function... for example, pneumonic cells are way different from hepatic cells. They don't have the same function, so they need to undergoing a process "to differentiate" themselves, according to their function. "Poorly differentiated", on the other hand, means that tumor cells do no resemble the tissue where they arose from, and that is, of course, not good at all. One last thing. When talking of hepatocellular tumor, you don't need to say "liver", because the prefix hepato means "liver".
