my kitten has developed a skin condition . any ideas what it could be (going to vets in the morning)

My kitten has been very I'll and just recovered from cat flu and over the last few days he has developed scaly skin on his ears and has just developed a black ringon his chin. He has been treated with antifungol since I got him so its not ring worm and he's been checked for ear mites and was all clear. I am not sure avout his chin I've read about feline acne but doesn't really look like the pictures I've seen and he doesn't use plastic dishes. He seems well in himself and everything else is fine. I've got a vets appointment tomorrow just curious what it is

Hello and welcome to TCS! any way you could post a picture of his problem?

I've tried up loading pictures but it won't let me. The scaly skin on the ear doesn't really show up. He's white and its been sunny but he's never been out. The black spot on his chin looks like a bruise or a mole on a human

Well hmmm....Glad you're getting him to the vet for a check.  I have no idea what it could be since my first guess was going to be acne and my second guess was going to be ringworm.  Let us know what you find out.
