Necrotizing sialometaplasia of palate

A patient with necrotizing sialometaplasia of the hard palate was treated with wide resection on a biopsy diagnosis of carcinoma. The literature on this recently identified entity is reviewed and the characteristic clinical features, histopathology and ultrastructure are summarized. To the best of our knowledge, no ultrastructural study concerning this entity has been previously reported. Unless recognized early, an extensive resection might be done needlessly.
