Introduction. Chondromyxoid fibroma is a slow growing and rare benign bone tumor. Its location in the craniofacial skeleton is not common, especially in the frontal sinus. Objectives. We present a long-term follow-up of a patient with a frontal chondromyxoid fibroma who was operated four years ago. We discuss the various differential diagnoses and possible treatments. Discussion. The differential diagnosis includes chondrosarcoma, myxosarcoma, myxoma and chordoma. From the radiological point of view, chondromyxoid fibroma must be always considered as a diagnostic possibility when a solitary bone lesion appears with expansion or cortical osteolysis, lobulated margins and intralesional septi. Treatment includes curettage or monoblock resection with immediate bone graft reconstruction. Radiation therapy alone must not be considered as the first therapeutic possibility. Conclusions. The benign nature of the tumor does not justify radical, unnecessary treatment. The subcranial approach is appropriate for lesions located in the frontal sinus. A clinical and radiological follow-up is needed to identify tumor relapse.
