Eosinophilic granuloma is a rare disease belonging to the Langerhans' cell histiocytosis group. It accounts for only 1% of all tumor-like lesions of bone. A 6-year-old girl presented with proptosis, and a mass and pain in her right eye. Cranial computerized tomography and magnetic resonance imaging revealed a mass in her right orbital area. The patient was operated through a right frontotemporal craniotomy and orbitozygomatic osteotomy. The tumour was totally removed. The postoperative course was uneventful. Histopathological examination revealed a diagnosis of eosinophilic granuloma with typical Langerhans cells and eosinophylic leucocyte infiltration. We report an orbital eosinophilic granuloma case, which is rarely seen, and discuss its clinical and pathological features.
