Long-Term Control of Primary Maxillary Sinus Transitional Cell Carcinoma with Surgery Followed by Radiotherapy: A Case Report - Abstract
Maxillary sinus malignancies are uncommon. They are separated into squamous and non-squamous cells histopathologically, with most of them being squamous cell carcinomas. Maxillary sinus transitional cell carcinoma is extremely rare and is classified as primary (sinusal origin) or secondary (non-sinusal origin). Herein, we report the long-term control of primary maxillary sinus transitional cell carcinoma with surgery followed by radiotherapy. A 31-year-old female patient was admitted with a complaint of swelling on the right side of her face. Paranasal sinus computed tomography showed a right-sided maxillary sinus tumor. Biopsy revealed transitional cell carcinoma, following which the patient’s right maxilla was totally removed with negative surgical margins. The final histological diagnosis was consistent with the previous diagnosis. The patient underwent postoperative radiotherapy. She remained disease-free at the 14-year follow-up. Knowledge concerning the treatment of maxillary sinus transitional cell carcinoma is limited. The combination of surgery and radiotherapy seems to be successful for this rare maxillary malignancy.
