My white cat has a black scab on her nose. Is it solar dermatitis?

Pet's info: Cat | Domestic Shorthair | Female | spayed | 11 months and 20 days old | 8.1 lbs

My white cat, Naomi has a black scab on her nose area. It appeared out of no where, she was fine in the morning & 2 hours later, she was sunbathing & I saw the black scab was already there. Could it be solar dermititis? Or something else? She never had any skin problems before. PS: This happened almost 1 1/2weeks ago & it has shrunk. She doesn't seem bothered by it & she goes through her day normally. 1st pic : 1 week ago - 2nd pic : 1 day ago Thank you.

Hello. I would watch this very carefully. Squamous cell carcinomas can occur on cats, but since Naomi is so young, I do not want to jump to conclusions. If this is not completely healed in another 7-10 day, or it repeatedly scabs, bleeds, scabs, then please have your vet take a very careful look at this. A small biopsy may be necessary to know if this is worrisome or not. Thanks for using Petco Pet Education Center, formerly Petcoach.
