Three Cases of Nasal Chondromesenchymal Hamartoma Occurred in Sinonasal Tract

Nasal chondromesenchymal hamartoma (NCMH) is a rare benign tumor of the sinonasal tract. Most NCMH has a benign nature and can be cured by complete resection. Only a few NCMH cases have been reported worldwide due to its rarity. Here, we report three cases of successfully treated NCMH, of which one case was diagnosed during preliminary ultrasound. All three cases were consistent with the benign symptoms of NCMH. Tumor in all of the cases were successfully treated through an endoscopic approach surgery and no evidence of aggressive recurrence was reported.
