Juvenile xanthogranuloma is the most common form of non-Langerhans cell
histiocytosis. It manifests clinically as a red-yellow papule, usually showing
spontaneous remission. The diagnosis is based on clinical and histological
findings. We report the use of dermoscopy ("setting sun" pattern) as an adjuvant
tool in the diagnosis of juvenile xanthogranuloma in a female patient presenting
with a 2-month history of a pre-auricular papule.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
