Cranial ossifying fibroma causing visual disorder.

Fibrous lesions of the head and the maxillofacial region are generally slow-developing benign tumors that may aggressively take course in clinical terms. These locally destructive lesions show a high recurrence rates unless they are removed gross totally. Sarcomatoid degeneration is also reported to develop in recurring lesions. Difficulties in the diagnosis, classification, and treatment make this entity complex for several years. These tumors are frequently seen among children and young adults. The maxilla and the mandibula are the 2 most common sites that the tumor originates. In our article, we discuss a 59-year-old man whose condition was diagnosed as an ossified fibroma revealing craniofacial extension. Accompanied by literature findings, it has been underlined that, as well as with the pathologic criteria, clinical features and radiologic images should be evaluated together for a specific diagnosis in fibrous lesions.
