<s>[INST] A boy child, aged 8 years, has a 3 cm circular white spot on his chest. Is it possible to stop Vitiligo from spreading beyond this area ? What are the chances of success in arresting the spread of this condition ? [/INST] As such treatment of the vitiligo is difficult, and the success rate is very low. Since there is only one patch that to on chest, which is usually covered area. Local steroid creams can be used to restrict the expansion of the lesion. There is home phototherapy using UVB lights that can be tried. If there is a chance, as the skin lesion is small, 3 cm, surgically the white spot can be removed as the spot is on the chest with a minimal scar. My vitiligo spot was 2cms and 3 cm son the knuckles, I got it removed and now even the scar is not visible, I think surgical removal is the right way to treat if the option is possible to prevent the spread! </s>
