Results There were 18 male and 12 female, and the average age of patients was 50.6 years old. Seventeen cases were adenoid cystic carcinoma, accounting for 56.7%. There were 17 cases clinically staged as Ⅲ, accounting for 56.7%. Distant metastasis and tumor recurrence were the main death reasons. The overall local recurrence rate was 30.0%, and distant metastasis rate was 26.7%. Conclusion Sublingual gland malignant tumors are rare and most of them are adenoid cystic carcinoma.
