Langerhans cell histiocytosis presenting as hypopigmented papules.

A 1(1/2)-year-old boy with Langerhans cell histiocytosis presented with a frontal bone mass showing features of eosinophilic granuloma. He subsequently developed multiple asymptomatic discrete hypopigmented papules on the face, trunk and extremities, which, on histology, were confirmed as Langerhans cell histiocytosis, a presentation hitherto unreported in literature. He responded well to surgery and chemotherapy.
