Basaloid squamous cell carcinoma of the maxillary sinus: a report of two cases.
Basaloid squamous cell carcinoma (BSCC) is a highly aggressive neoplasm and a histologically distinctive variant of squamous cell carcinoma. Since the first description by Wain et al. in 1986, only 18 cases with BSCC in the nasal cavity or in the paranasal cavity have been reported in the English literature. We report herein two cases of BSCC of the maxillary sinus. Case 1 was 78-year-old man, who received preoperative radiotherapy and operation. He was alive without disease for 25 months after the operation. Case 2 was a 60-year-old man who received radiotherapy without operation. He died of lung metastasis 6 months after the initial diagnosis. We reviewed the clinical features of BSCC from the literature.
