A 11-year-old child presented to our outpatient department with slowly progressive depigmented patches on face for past 2 years. On examination, loss of pigmentation was noted on forehead, periocular region, bridge of nose, and lips. White hairs of right eyebrow were also noted. Lesions were asymptomatic and non-scaly (Fig. 17.1). There was no history of pre-existing dermatosis or chemical application at the site. Her routine laboratory parameters including thyroid profile were within normal limits. Her mother has similar lesions on her hands. Based on the case description and the photograph, what is your diagnosis?
