Abstract
Nasal and sinonasal inverted papilloma is an uncommon benign tumor, which is complicated by malignancy in approximately 10% of cases. Preoperative differential diagnosis between inverted papilloma with or without squamous cell carcinoma may be useful in planning the method of surgery. However, for squamous cell carcinoma associated with IP, the presence of squamous cell carcinoma may be unknown until after removal of the entire diseased mucosa, because some patients with squamous cell carcinoma associated with inverted papilloma had no evidence of squamous cell carcinoma in their initial biopsy specimens. We report a case of a voluminous and locally advanced squamous cell carcinoma arising from sinonasal inverted papilloma of a 64-year-old man, with review of literature. The patient underwent oncological surgery, with total excision of the tumor by lateral rhinotomy approach, and received adjuvant radiotherapy.
