Chondromyxoid fibroma of the nasal bone with extension into the frontal and ethmoidal sinuses.

Chondromyxoid fibroma is a rare benign tumour whose histological appearance may easily be misinterpreted as chondrosarcoma. It has a tendency to recur locally unless completely excised. A rare case of the tumour affecting the nasal bone with extension into the frontal and ethmoidal sinuses and impingement on the cribiform plate is presented. Complete excision was achieved by the craniofacial resection approach.
