Intraoral malignant minor salivary gland tumors are relatively rare, but minor salivary gland tumors in adolescents are extremely rare. This report describes the case of an acinic cell carcinoma occurring in an adolescent. The patient was a 9-year-old boy who became aware of a tumor on the anterior floor of his mouth and had a checkup in this department. A benign tumor was suspected because of the clinical course and the imaging results the tumor was initially enucleated surgically. The pathological diagnosis of the resected tumor was an acinic cell carcinoma and additional tissue was resected. After the second operation the margin was pathologically negative, so the patient was observed in the outpatient department without either chemotherapy or radiation. An acinic cell carcinoma is generallyt hought to be a low grade tumor in the salivary gland tumor, but it is pathologically categorized into three grades. An intraoral tumor in the minor salivary gland tumor is very rare, and there is no uniform treatment and this patient will require a careful follow-up in the future.
