We report a case of cyst of the papilla palatina. A 70-year-old woman was referred to our department to receive consultation for a swelling of the anterior hard palate. On intraoral examination, we confirmed a defined swelling, measuring approximately 13 × 10 mm, in the soft tissue of the palatine papilla. A computed tomographic scan showed pressure-induced enlargement of the incisive fossa. We removed a cyst with the patient under general anesthesia. Histopathological examinations revealed inflammatory cell infiltration of the cyst wall, which was lined by stratified squamous epithelium, ciliated columnar epithelium, and simple cuboidal epithelium. We diagnosed a cyst of the papilla palatina based on clinical, radiological, and histopathological findings. After operation, there has been no sign of recurrence.
