Abstract
We reported a rare case of Basaloid squamous cell carcinoma of the maxillary sinus. The patient was a 60-year-old female with a swollen hard palate. A smooth large mass protruding into the hard palate and spreading to the nasal cavity was found. A CT scan and MRI demonstrated a mass occupying an area extending from the ethmoid sinus to the hard palate. No metastatic lesions were detected. A biopsy specimen revealed basal cell carcinoma. Excision of the tumor was performed. Based on surgical findings, the medial wall of the maxillary sinus was considered to be the original focus of the tumor. Microscopic studies confirmed the diagnosis of basaloid squamous cell carcinoma. The clinical features of basaloid squamous cell carcinoma are discussed.
