I'm sorry that your question wasn't answered in a timely manner. Can you upload a photo of this lesion to our conversation? You can use the paperclip icon in the toolbar above your message box (if that icon is visible) or you can use an external app such as or I can be more accurate for you if I can see what you're seeing. I believe you're seeing an epidermal collarette which is a roughly circular skin lesion most often indicative of a Staphyloccocal infection. These start out as pustules and spread out in a circular manner. The center quiets down and hyperpigments while the rim of the collarette remains inflamed and actively infected.

You'll need her vet's help. That's an unusual skin lesion to appear suddenly. I'm too far away to diagnose it properly. For now you can cleanse the area with over the counter Hebiclens (chlorhexidine) and you'll need to apply an E-collar or neck brace available in pet stores to keep her away from the lesion.
