Cellular Classification of Paranasal Sinus and Nasal Cavity Cancer
The most common cell type for paranasal sinus and nasal cavity cancers is squamous cell carcinoma. Minor salivary gland tumors comprise 10% to 15% of these neoplasms. Malignant melanoma presents in <1% of neoplasms in this region. Some 5% of cases are malignant lymphomas.[1,2]
Esthesioneuroepithelioma, sometimes confused with undifferentiated carcinoma or undifferentiated lymphoma, arises from the olfactory nerves.
Chondrosarcoma, osteosarcoma, Ewing sarcoma, and most soft tissue sarcomas have been reported for this region.
Inverting papilloma is considered a low-grade benign tumor with a tendency to recur and, in a small percentage of cases, to transform into a malignant tumor.
Midline granuloma, a progressively destructive condition, involves this region as well.References
