Victim of dog abuse?

Koko has a huge swelling on the side of his face. We were afraid it was cancer, but the vet seemed to think that it was a sialocele (salivary gland cyst from breakage of the duct). Joel reminded me that I had accidentally kicked Koko in the head a couple days ago, so this is probably the cause. The cytologist thought it was a hyperplastic lymph node and didn't see evidence of the salivary gland involvement. We have a surgical consult next week. He's a sad baby.
