Diverticular Pouch of the Buccal Mucosa: A Rare Case Report.

Diverticular pouch in the oral cavity is a rare disease, and its etiology is unclear. The authors present a rare case of diverticular pouch in the buccal mucosa. A 79-year-old man visited our hospital with a chief complaint of food impaction in the right buccal mucosa. Intraoral examination revealed a pouch just inferior to the parotid papilla. Histopathological examination after excisional biopsy showed that the epithelial cells lining the pouch were continuous with the mucous membrane and a diagnosis was made of diverticular pouch of the buccal mucosa. Twenty-five months after the patient's initial visit no recurrence has been noted. Further clinico-pathological studies are required to understand diverticular disease in the buccal mucosa. This case might help dentists to become more aware of these lesions and collect data for further investigations.
