The aim is to present a unique clinical case of a 62-year-old male with an ossifying fibroma (OF) in the left orbit. He presented with a slow-growing mass with bone consistency which easily shifted with palpation. After removal, it was given the histopathological diagnosis of osteoma. However, the lesion grew back rapidly and it became even larger 4 months later. After a computed tomography scan with a contrast medium, another surgery was performed. The histopathological diagnosis of the recurrent lesion was an epidermal cyst with secondary degenerative changes. As both diagnoses did not fit the clinical picture, we sent the material from both surgeries for a secondary assessment. The final histopathological diagnosis was OF. OF should be included in the differential diagnosis of benign lesions in the orbit with aggressive behavior.
