RESUMO
We report the case of a 6-month-old Hispanic boy with a 4-month history of widespread pruritic hypopigmented papules mimicking lichen nitidus. The final diagnosis was multisystem non-risk-organ Langerhans cell histiocytosis (LCH), with cutaneous and multiple bone involvement. With this patient and others previously reported in the literature, we suggest an early biopsy of the hypopigmented rash in children.

Lichen nitidus is an uncommon lichenoid dermatosis that could be defined as multiple, separated, shiny, pinpoint, pale to skin-colored papules. Palmoplantar lichen nitidus is a quite rare variant of lichen nitidus. It is hard to make a diagnosis of palmar lichen nitidus when there are no lesions elsewhere on the body. There are some dermoscopic features defined for both palmoplantar and non-palmoplantar lichen nitidus that might be useful to facilitate the diagnosis before histopathological examination. Herein, we report a case of a 24-year-old man diagnosed with isolated palmar lichen nitidus with dermoscopic features and histopathological confirmation.
