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".
