· Autoimmune disease

· The disease is systemic and affects all exocrine glands including those of the skin,vagina,lung and pancreas.

· Lymphocytes(CD4) infiltrate the glands and cluster around duct replacing acinar cells

· Progressive destruction of secretory acini

· Proliferation of some duct tissues as epimyoepithelial islands(myoepithelial syeloadenitis)

· Finally destruction of acini and replacement of the whole gland by dense lymphocytic infiltrate

· Auto antibodies-Salivary duct antibodies,Rheumatoid factor,SS-A,SS-B,Rheumatoid arthritis precipitin
