Abstract
9 cases of lymphocitary chronic nodular phlogosis of the parotid gland are studied. The different pathogenetic factors are discussed and the relationship with Hashimoto thyroiditis (histologically similar) is examined. On the basis of microscopical investigations, showing the presence of intraparotidean lymphnodes (including salivary epithelial elements), these « pseudo-tumoral nodular hyperplastic » aspects are suggested to be derived from chronic phlogistic hyperplasy of the pre-existent lymphnodes. The morphological alterations of the parotidean glandular elements and the eventual malignant transformation are pointed out.
