[Contribution to the etiology and pathogenesis of chronic recurring parotitis].

Chronic, recurrent parotitis was classified as a disease of the salivary glands of bacterial and inflammatory origin. Forty biopsy specimens of the parotoid gland taken from patients with chronic, recurrent parotitis were examined via light and electron microscopy; virus or bacteria could not be identified. The pathomorphologic findings with chronic, recurrent parotitis correspond basically with those of an experimental ligature of the ganglia. The pathogenesis was discussed. The results of the investigation indicated that, in terms of the pathogenesis, chronic, recurrent parotitis represents a special form of electrolytic and/or obstructive sialadenitis.
