A 14-year-old boy comes to the physician because of multiple patches on his trunk and thighs that are lighter than the rest of his skin. He also has similar depigmented lesions on his hands and feet and around the mouth. The patches have gradually increased in size over the past 2 years and are not associated with itchiness, redness, numbness, or pain. His family emigrated from Indonesia 8 years ago. An image of the skin lesions is shown. What is the most likely cause of this patient's skin findings?
