Supplementary Material for: Wilson Disease and Nevus of Ota in a Child – Case Report

Introduction
Wilson's disease is a rare autosomal recessive disorder that disrupts copper metabolism. It presents with distinctive ocular manifestations. Oculodermal melanosis, commonly referred to as Nevus of Ota, is a painless condition characterized by hyperpigmentation in and around the eye. In this case report, we describe the unique occurrence of both conditions in this pediatric patient.
Case presentation
A ten-year-old girl exhibited classic ocular signs associated with Wilson's disease, including Kayser-Fleischer rings and sunflower-type cataracts. Additionally, she displayed unilateral confluent gray-blue hyperpigmentation consistent with a nevus of Ota. As of now, the patient remains asymptomatic, with preserved visual acuity.
Conclusion
To the best of our knowledge, this case represents the first report of Nevus of Ota in a child diagnosed with Wilson's disease.
