Necrotizing sialometaplasia of the palate. Ulcerative or necrotizing stage of leukokeratosis nicotina palati?
A typical case of the recently described tumor-suspect lesion, necrotizing sialometaplasia (NS) of the palate, in a 54-year old Caucasian male is presented. Results of complete blood- and urinanalysis including serum electrophoresis and labial salivary gland biopsy strongly pointed at a local etiologic factor. Previous statements that the disease represents a new entity are questioned. The present authors favor the idea that NS is the necrotizing (ulcerative) or terminal stage of leukokeratosis nicotina palati (nicotinic stomatitis). It is of particular importance that this lesion is not diagnosed as a malignancy, as it heals spontaneously and uneventfully.
