A Case of Chondromyxoid Fibroma Observed in the Nasal Cavity

Chondromyxoid fibroma (CMF) is an extremely rare, benign cartilaginous tumor found in the craniofacial region. It is often misdiagnosed due to its rare occurrence in the nasal and paranasal sinus; moreover, it has similarities with other cartilaginous tumors, showing the same radiologic and histopathologic features. A 62-year-old female consulted our clinic with the chief complaint of a left nasolabial mass of one-month history. The mass was located in the nasal cavity: from there it extended anteriorly to the anterior nasal spine, posteriorly to the end of the hard palate, and laterally to the maxillary sinus. The nasal septum was deviated to the right side due to the mass effect. Complete removal of the mass was conducted via the modified endoscopic Denker’s approach, and the diagnosis of CMF was established. During the 36-month follow-up, no recurrence was observed.
