I'm sorry that your question wasn't answered in a timely manner and I regret that I - and most vets - aren't allowed to communicate by phone with customers. Can you upload a photo of this patch 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.

The color change indicates abnormal skin under the fur in most cases. Occasionally a genetic coloration abnormality exists but that shouldn't be sensitive to the touch. Will he allow your parting the gray/white hairs and looking closely at the skin? If not, his vet will need to shave away the hair and take a good look at the skin. Inflammation is likely because it's sensitive to the touch. I might find a cyst or other neoplasm, ingrown hairs and secondary infection, or anatomical anomaly.
