Erdheim-Chester disease (ECD) is a rare, systemic, nonLangerhans cell histiocytosis. In approximately 25% of the cases there is cutaneous involvement. The diagnosis should be considered in patients with atypical or extensive xanthalasmata-like lesions with a normal lipid profile or systemic symptoms like bone pain or diabetes insipidus. ECD and Langerhans cell histiocytosis (LCH) can overlap (ECD-LCH overlap syndrome). Both seems to be associated with a BRAFV600E mutation, which suggests a common origin.
