[Salivary gland infarction (necrotizing sialometaplasia) caused by intraglandular circulation disorders in the rat parotid gland. Experimental study].

The morphologic alterations with necrotising sialometaphasia are very characteristic microscopically. The false diagnosis of a squamous cell carcinoma or a mucoepidermoid tumor is possible if the examiner is not familiar with the signs of necrotising sialometaplasia. Vascular insufficiency with a zone of relative and absolute ischemia has been discussed as the etioloic factor (Donath 1979). In experimental studies of the parotid glands of rats following intraglandular ligature of a vessel, a position was taken regarding the pathohistology described as the pathogenesis of necrotising sialometaplasia (salivary gland infarct).
