Hello. This could just be an odd looking cyst or wart, but it does not look overly aggressive or worrisome to me. Just point this out to your veterinarian at Chainz's next veterinary visit so it is documented in the record. At some point, removal may be recommended, but definitely not at this point in time. Thanks for contacting Petco Pet Education Center, formerly Petcoach.
