The juvenile xanthogranuloma (JXG) is a benign, generally asymptomatic proliferation of non-Langerhans histiocytic cells. It usually presents as a yellowish papulonodule in a child.
Juvenile xanthogranuloma typically presents as a solitary lesion in a young child usually under 1 year of age, but it can be congenital and multiple lesions may occur. It is most common on the head and neck.
Rarely, JXG may occur in extracutanous locations. In one meta-review, the incidence of systemic manifestations was 0.75% (22/2949) and of ocular manifestations 0.24% (7/2949).
