title: [Orbital localization of lymphocytic macrophagic histiocyosis (Rosai's sinusal histiocytosis].
abstract: The authors report the fifth case in the literature of an orbital presentation of macrophagic lymphocytic histiocytosis or sinusal histiocytosis. This disease which usually presents in the ganglia is accompanied by a characteristic histological appearance dominated by the taking up of blood cells (lymphocytes, plasmocytes, erythrocytes) by macrophages. Its evolution is benign but its aetiology remains unknown and its treatment uncertain.
