Spindle cell carcinoma is considered a subtype of squamous cell carcinoma that has a sarcomatoid appearance. In the head and neck region, cases of spindle cell carcinoma of the larynx have occasionally been reported. However, spindle cell cacrcinoma of the maxillary sinus is extremely rare. We describe a case of spindle cell carcinoma of the maxillary sinus in a 53-year-old woman. Surgical treatment was performed under the clinical diagnosis of a maxillary neoplasm. During the operation, a biopsy specimen was taken, and the histopathological diagnosis was a spindle cell carcinoma. The lesion was removed under general anesthesia. Radiotherapy and chemotherapy were additionally given to prevent recurrence and metastasis of the tumor.There has been no evidence of recurrence as of 5 years 6 months after surgrey.
