An unusual buccal adenoma with extensive squamous metaplasia and cyst formation.
Salivary gland tumors are the second most common neoplasm of the mouth following squamous cell carcinoma, and account for a significant proportion of oral tumors. We report a case of an unusual adenoma that presented as a solitary intraoral buccal mass in a 28-year-old male patient. The tumor was intrepreted as an unusual pleomorphic adenoma because of the absence of connective tissue changes and presence of metaplastic epithelial change which is an occasional finding of such tumors. Moreover, the presence of cystic structures with papillary infoldings filled with some crystals and pearl-like keratinized material were also salient features.
