Abstract:
Sialadenoma papilliferum (SP) is a rare benign salivary gland tumor. Mostly, it occurs in association with minor salivary glands, especially at the posterior palate. The typical clinical features of this tumor are asymptomatic, slow growing, broad-based papillary projections of the oral mucosa. Here, we report a case of SP at the posterior palate of a 57-year-old woman. After incisional biopsy, complete excision of the tumor was performed. Histopathological examination showed parakeratinized stratified squamous epithelium which exhibits exophytic papillary projections along with underlying fibrocollagenous vascular connective tissue containing ductal structures lined by inner columnar cells and outer cuboidal cells. Based on these findings, the final diagnosis of SP was given. No recurrence was observed at 12 months follow-up. Reviews of previous case reports, clinical and histopathological differential diagnosis are discussed.
