<prompt> Histologically intense lymphocytic infiltration of the gland replacing the acinar structures, but preserving the lobular architecture seen in:Mucoepidermoid carcinoma.Epithelial- myoepithelial carcinoma.Sjogren syndrome.Myoepithelioma  <response>: The three types of histologic alterations seen in Sjogrens syndrome are as follows: Intense lymphocytic infiltration of the gland replacing the acinar structures, but preserving the lobular architecture.Proliferation of the ductal epithelium and myoepithelium to form epimyoepithelial islandsAtrophy of the glands sequential to the lymphocytic infiltration.
