Abstract

Conclusion: Malignant tumors of Stensen’s duct are often squamous cell carcinomas. Surgery is the treatment of choice, and maintaining an adequate safety margin and performing parotidectomy may help to reduce postoperative recurrence. Objectives: Since malignant tumors of Stensen’s duct are extremely rare, the number of cases is limited in single-facility studies, making it difficult to perform a sufficient number of clinical examinations. Therefore, we reviewed 26 cases with Stensen’s duct malignancies to examine their clinical features. Methods: We conducted a retrospective study of 26 cases with Stensen’s duct malignancies, including 1 patient whom we treated and 25 cases previously reported in the English literature, and analyzed their clinical parameters, including age, sex, affected side, chief complaint, tumor size, histopathology, treatment method, and treatment outcome. Results: Most cases were diagnosed in patients between 40 and 69 years of age. The chief complaint was swelling in the cheek in 24 patients, in 14 of whom the swelling was painful. The most common tumor diameter range was 10–19 mm. Squamous cell carcinoma was the most frequent histopathology. The recurrence rate in surgical patients who did not undergo parotidectomy was 60%, whereas in patients who underwent parotidectomy, the recurrence rate was only 7%.
