Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Luna! Very strange! It could have been an abscess and the pictures of are hardened inflamed tissue or it could have been a salivary stone or a foreign body that migrated in to the subcutaneous tissues. it is very odd. You can bring it and Luna to the vet Monday and have them look at her and dissect it to see if they can give you a definitive answer. I wish you the best!
