[Reparative giant cell granuloma with orbital involvement].

A 54-year-old woman was evaluated for a left orbital mass that had been present for one year. Examination showed mild superolateral displacement of the normal left eye and a firm medical orbital mass. A complete resection of the lesion was accomplished via a combined neurosurgical, otolaryngologic and ophthalmologic superior orbital approach. Histologic features of the mass were consistent with giant-cell (reparative) granuloma. However, it has to be pointed out that fibroosseous lesions with giant-cells display similar histologic features and require clinicopathologic correlation including radiographic studies for final diagnosis.
