This could be a skin infection caused by a fungus or bacteria or and old injury or bite and in worst case scenario it could be a tumor. Please have this examined by your veterinarian. If he suspects a tumor, he will likely want to remove it and send it in to determine whether it is malignant and your dog needs further treatment. If it is an infection your dog may need an antifungal or antibiotic ointment. It may just be a scab from an old wound and might need no treatment. Your vet will be able to determine that with a hands-on exam.
