My son has developed a small white patch on his chick for last one month. We want to make sure whether it's an fungal infection or something like vitiligo as my wife has vitiligo since her childhood. The patch is not increasing in size nor spreading rather having a constant size from the very beginning. It's rather a little rough surface which resulted into itching in early days. I am sending the photo of the area of his face for you to have a look. Please look into the matter so that we can take the needed and immediate steps. Regards.
