Congenital cutaneous lymphadenoma.

abstract：:Xanthogranulomas are benign lesions composed of macrophages in which some of the cells have vacuolated cytoplasm. They commonly occur in children, referred to as juvenile xanthogranulomata, and are histopathologically characterized by the presence of Touton giant cells. Xanthogranuloma can also occur in adults. A woma...
