The patient presentsd with total melanonychia with splitting and fissuring of the nail plate on the right thumbnail. Hutchinson’s sign was indicated on the proximal and lateral nail folds. neous repigmentation is more likely to be the cause of repigmentation than chemotherapy. Unfortunately, our patient was lost for further follow-up. When pigmented lesions appear in vitiligo universalis patients, it is easy to consider pigmented skin disorders such as melasma. Sudden repigmentation of vitiligo universalis is a rare event that must be evaluated carefully to avoid misdiagnosis.
