Dermoscopy of Langerhans cell histiocytosis

An 11-month-old boy was brought by parents with 2-months' history of asymptomatic rash over the trunk and neck associated with on-and-off fever. Cutaneous examination revealed multiple discrete and grouped erythematous-to-skin-colored nonscaly papules of size varying from 1 × 1 mm to 3 × 3 mm over the trunk and neck (Fig 1). The child also had scalp scaling and generalized lymphadenopathy.
