Description
Summary:Necrotizing sialometaplasia is a benign self-limiting inflammatory reaction that mainly occurs in the minor salivary glands of the hard palate, mimicking malignancy. Case 1 involved a 32-year-old man with a painful ulcerated swelling in the hard palate lasting 3 weeks. Case 2 involved a 63-years-old man presenting a painless ulcer of 2-week duration located in the hard palate. Microscopically, both cases showed salivary glands with preserved lobular architecture containing acini with variable degrees of degeneration and foci of ductal squamous metaplasia. Both lesions regressed completely after incisional biopsy. Oral clinicians and pathologists should consider necrotizing sialometaplasia when evaluating oral ulcerated lesions located in the hard palate.
