Intraoperative images depicting a large fleshy left nasal mass (a), which was endoscopically debulked with a microdebrider (Skimmer) (b). The stalk of the teratoma (asterisk) was revealed to be arising from the roof of the nasal cavity (c). Postresection image (d) showing the site of tumor origin (arrow) in relation to the turbinates. ST, superior turbinate; MT, middle turbinate; IT, inferior turbinate.

Intraoperatively, a large left nasal mass was noted (Figure 2(a)), which extended anteriorly to the nasal vestibule and posteriorly to the posterior choana. The tumor was gradually debulked and removed endoscopically with a microdebrider (Skimmer ) (Figure 2(b)). The stalk of the tumor was traced to be arising from the roof of the nasal cavity medial to the superior turbinate (Figures 2(c) and 2(d)).
