Langerhans cell histiocytosis mimicking molluscum contagiosum: A case series.

Langerhans cell histiocytosis (LCH) is a disorder characterized by accumulation of Langerhans-like cells in one or various organs. A correct staging work-up is essential since there are multiorgan presentations with a poor prognosis. We report three patients with LCH skin lesions mimicking molluscum contagiosum in association with both high and low risk organ involvement. This peculiar cutaneous presentation can be a clue for the diagnosis of LCH, a disease with potentially severe systemic involvement.
