Necrotizing sialometaplasia in the setting of acute and chronic sinusitis

Necrotizing sialometaplasia is a benign lesion that may be mistaken for mucoepidermoid or squamous cell carcinoma. A case report is presented in which necrotizing sialometaplasia was noted as an incidental finding in the setting of acute and chronic sinusitis. It is critical to recognize the lesion as benign so as to avoid overdiagnosis and overtreatment.
