Pediatric Benign Nasal Triton Tumor: Its Diagnosis and Treatment.

[BACKGROUND] Benign triton tumor (BTT) is a rare, benign peripheral nerve tumor typically affecting young children. While most found in the brachial plexus or sciatic nerve, BTT can occur in other various locations, including cranial nerves.

[METHODS] Case report and review of literature.Results/Case:This report describes an infant who showed a swelling localized at nasal pyramid. Patient underwent ultrasound and magnetic resonance imaging. Following, a surgical treatment was performed and histological examination supported the diagnosis of a BTT (neuromuscular choristoma).

[CONCLUSIONS] BTT is a very rare tumor at the head and neck area in pediatric age. Given the unusual presentation and rarity of this tumor, this case highlights the importance of considering BTT in the diagnosis of pediatric nasal masses. Imaging of this lesion is fundamental to plan the surgical therapy. To date, present patient is the first case in which this neoplasm is localized to the nasal pyramid.
