Histological study of parotid, submaxillary and von Ebner salivary glands in chronic alcoholics.
Samples from parotid, submaxillary, and von Ebner salivary glands of six chronic alcoholic individuals who had died of alcoholic hepatic cirrhosis were analyzed by topographic and histochemical routine stains and marked for cytokeratins; two normal adult individuals were used as control. Modifications in the acinar cells were found, but the most evident changes were observed in the ductal system: enlargement of major ducts, heterogeneous expression of cytokeratins and athrophy in epithelial cells, desquamated cells and stasis of content, and ductal hyperplasia in von Ebner glands. The lymphoplasmocytic infiltration does not represent the typical lymphocytic focus on Sjögren's syndrome or other connective tissue pathologies. Our findings indicate that functional and structural variations are produced both in serous acini and ducts parotid, submaxilar and von Ebner glands affected by alcoholic sialosis.
