These are patchy Vitiligo marks and as these are not totally white so it indicates there are underlying Melanocytes which are not totally absent , and at this stage treatment can cure patchy Hypopigmented areas .
Vitiligo is clinical diagnosis , biopsy is usually not required , and done only in cases where Physician is in doubt about diagnosis .
Systemic Phototherapy cure more than 70 percent of cases , and meanwhile Micropigmentaion can also helpful , she should get treatment at this stage please .
Please ask Dermatologist and Discuss about Systemic Photo therapy please .
Do you have any more questions?
