• Necrotizing sialometaplasia occurred in a 46-year-old woman. This is an uncommon benign disease that typically begins with an ulcerated lesion on the hard palate and surrounding tissues. Clinical and microscopic findings show obvious similarity with a malignant neoplasm. Necrotizing sialometaplasia is a benign minor salivary gland disease. It is important since it may easily be confused with squamous cell carcinoma and mucoepidermoid carcinoma.
