Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Spontaneous regression over years

Juvenile xanthogranuloma is a benign non-Langerhans histiocytosis of infants and children with yellow-orange papules and Touton giant cells. Lipids are normal and lesions usually involute over 3 to 6 years. Ocular involvement in multiple lesions in infants warrants eye review.
