Necrotizing sialometaplasia (also spelled necrotising sialometaplasia) is a benign ulcerative lesion found mostly on the posterior hard palate. It is due to a necrosis of minor salivary glands due to trauma (often palatal infiltrations of local anaesthetic or trauma during intubation).

Often painless, condition is self-limiting and should resolve in 6–10 weeks.

Differential diagnosis[edit]

Differentiation between this and SCC would be based on a history of recent trauma or dental treatment in the area.
