Thanks for using Petco Pet Education Center, formerly Petcoach! This may be a benign or malignant growth. This could even be an infection. This cannot be completely assessed just by looking at pictures and usually requires sampling such as fine needle aspiration to determine its origin. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have her evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!
