Otolaryngeal mucoepidermoid carcinoma:a clinicopathological study of 15 cases

Purpose:To study the clinicopathological features of otolaryngeal mucoepidermoid carcinoma, and to elucidate its diagnosis and differential diagnosis. Methods:The clinical data were reviewed retrospectively and immunohistochemical stains were performed in 15 cases of mucoepidermiod carcinoma.Results:The 15 patients were all male with average age of 55 years. Two histological types were found: well differentiated (14 cases), poorly differentiated (1 case). The tumor cells were positive for CK,CK8,EMA,CEA.Conclusions:Mucoepidermoid carcinoma of otolaryngeal tumor is a rare tumor. It can be differentiated from other otolaryngeal tumors based on the histopathologic features and immunohistochemical findings. Histological type of the tumor is important for clinical therapy and prognostic evaluation.
