NCIt definition : A rare, keratinizing or non-keratinizing squamous cell carcinoma arising from the
mucosal epithelium of the nasal cavity or the paranasal sinuses. It affects most often
the maxillary sinus. Less frequently, it arises from the nasal cavity, ethmoid sinus,
sphenoid sinus, and frontal sinus. Symptoms include nasal fullness, epistaxis, rhinorhea,

earlier than patients with maxillary sinus carcinoma and have a better prognosis compared
to the latter group.;
