Non-ulcerated Necrotizing Sialometaplasia: A case series

Necrotizing sialometaplasia is an uncommon, locally destructive inflammatory condition that most frequently affects the minor salivary glands of the palate, although salivary glands at other sites can also be affected. Its clinical presentation is generally characterized by the presence of a painful, ulcerated swelling, but in the early stages, it might not be ulcerated which makes its diagnosis very challenging. Although it is a benign, self-limited condition, care must be taken during diagnosis, as it can mimic malignant processes, both clinically and histologically. Here we report three uncommon cases of non-ulcerated necrotizing sialometaplasia with its clinical and histopathological characteristics.
