Thanks for using Petco Pet Education Center, formerly Petcoach! This could be ringworm which is a fungal infection which needs to be treated and also can be contagious to humans. I highly recommend that you have her evaluated by your veterinarian for further assessment and treatment. Also, avoid contact with this lesion for now. Good luck!
