Abstract
Verrucous carcinoma（VC）is a low-grade cancer characterized by slow growth and weak invasion compared to squamous cell carcinoma. In the head and neck region, it often occurs in the oral cavity and larynx. It is rare at about 1％ in nasal sinus tumors.
The present case was a 77-year-old man. He was admitted to our hospital with nasal congestion due to a left nasal cavity tumor. He had become aware of this tumor 10 years ago. A biopsy of the tumor was performed, and the pathological result was VC. We diagnosed cT3N0M0，Stage Ⅲ and performed the operation. Although a lateral rhinotomy approach was also considered, the operation space was secured by removing the septal cartilage, vomer, and ethmoid, and the tumor could be removed endoscopically. There is no consensus on the use of chemoradiotherapy for VC. Surgical resection is considered the first choice because there are reports of anaplastic change by irradiation.
