xanthogranuloma, juvenile (JXG) 

A benign proliferation of single or multiple, small yellowish-brown papules or nodules in the skin and the anterior uvea, especially the iris. The condition mainly appears in young children, although it may occur in adults. The lesions consist of dermal infiltration by histiocytes, lymphocytes, eosinophils and Touton giant cells. The skin lesions increase in size and number but eventually regress spontaneously into an atrophic scar, otherwise they may need to be treated by excision or corticosteroid injection. In the eye it is commonly associated with hyphaemia (in the anterior chamber), uveitis and secondary glaucoma with visual loss. Therapy includes topical and systemic corticosteroids. Syn. juvenile nevoxanthoendothelioma.
