Any idea what this is ...

He is indoor cat only with us for more than 1 year, never had any problems. Lately he got skin acne under his Chin, which went away... now this on his cheek...

any help...? ideas? what it is .. how to treat it?

T H A N K   Y O U !

It looks like an abscess that burst - was the area swollen at all before?  I'd take him to the vet, just to be sure.  He might need antibiotics.

I don't think so it was swollen. It started as a small spot and then got bigger her it is zoom 

It looks raw, which means there is a danger of infection. I would see my vet.
