Necrotizing sialometaplasia (NS) is an uncommon, benign self-limiting lesion, locally destructive and an inflammatory condition that largely affects minor salivary glands and the major salivary glands in up to 10% cases.  A 19 year old male patient with bilateral painful ulcerative lesions over soft palate extending to the hard palate was presented to our department. Histopathological examination of punch biopsy revealed Pseudoepitheliomatous hyperplasia with replacement of the seromucinous lobules by aggregates of squamous cells and associated dense acute inflammation was observed. The pathogenesis of NS is unknown but is believed to be due to ischemia of vasculature supplying the salivary gland lobules. A simple biopsy is required to confirm the histological diagnosis and to rule out more serious disease processes. It is a self-limiting disease process and requires no specific treatment.
Key words: Inflammation, Ischemia, necrotizing sialometaplasia, pseudoepitheliomatous hyperplasia, self-limiting disease..
