Sialadenoma papilliferum (SP) classified under the ductal papillomas by the WHO is a rare benign tumor of minor salivary glands. It is a rare lesion of salivary glands predominantly affecting the minor glands. It has characteristic exophytic and endophytic clinical growth pattern. Histopathologically, it is characterized by papillary projections supported by fibrovascular connective tissue core and infiltrated with mixed inflammatory cells. The ductal lining epithelium of double-layered cells of luminal layer of tall columnar cells and a basilar layer of small cuboidal cells shows additional papillary projections into the lumen. We report a case of SP of mid palate.
