Description
Background Basal cell adenoma is a benign neoplasm of the salivary glands. This tumor usually arises in the major glands, with the parotid being the most frequent site of occurrence, while it is rare in the minor salivary glands. We report a case of basal cell adenoma of a minor salivary gland on the palate. Case The patient was a 68-year-old man. Intraoral examination revealed a mass measuring 20×20 mm that was elastic-hard, dark violet, non-ulcerated, and covered the normal mucosa. Computed tomography scan and magnetic resonance imaging (MRI) both showed a mass situated in front of the soft palate. The T1-weighted MRI revealed tumor isointensity, and the T2-weighted image showed tumor hyperintensity. The clinical diagnosis was palate tumor, and excision was performed under general anesthesia. Histopathological examination revealed that an encapsulated mass had grown under the epithelium and indicated a diagnosis of basal cell adenoma. Discussion Although no recurrence has been detected in the 3 years and 6 months of follow up, there was a case of malignant transformation of a basal cell adenoma reported. Therefore, careful follow-up observation will continue to be important.
