NCI 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, pain, and paresthesia. Patients with nasal squamous cell carcinoma usually present earlier than patients with maxillary sinus carcinoma and have a better prognosis compared to the latter group. [1]
