Dermoscopic feature analysis of different skin lesions in Langerhans cell histiocytosis

Dermoscopy was used to investigate skin lesions in 15 children with Langerhans cell histiocytosis (LCH). Purplish-red globules or patches could be seen in different rashes under dermoscopy, and histopathology showed extravasation of red blood cells. The dermoscopy findings closely correlated with the histopathology results. Purplish-red globules or patches could be useful as important dermoscopy features for the differential diagnosis of LCH.
