Chondromyxoid fibroma of the nasal bone with extension into the frontal and ethmoidal sinuses: Report of one case and a review of the literature

Chondromyxoid fibroma is a rare benign tumor that usually occurs in the lon g bones. A 50-year-old patient presented with chondromyxoid fibroma of the nasal bone with extension into the frontal and ethmoidal sinuses. This is t he fourth case reported to date in the literature. The clinical manifestati ons of the tumor were very limited, and the appearance at rhinoscopy was mi sleading. Radiologic imaging showed a soft tissue lesion invading the adjac ent bony structures and the dura mater. Surgery was performed by a combined team of otorhinolaryngologists and neurosurgeons, and total excision of th e tumor was achieved. The histologic diagnosis of this tumor is difficult b ecause of its similarities to chondrosarcoma.
