Recurrent pleomorphic adenoma of the submandibular gland: a clinical and pathologic study of 15 cases

Abstract

Abstract: PURPOSE: To investigate the clinicopathological feature of recurrent pleomorphic adenoma of the submandibular gland, and discuss its diagnosis, treatment and prognosis. METHODS: From June 2005 to June 2017, the clinical data and pathological features of 15 cases of recurrent pleomorphic adenoma of the submandibular gland treated in Shanghai Ninth People's Hospital were reviewed and analyzed retrospectively. RESULTS: Among 15 cases, 4(26.67%) were male while 11(73.33%) were female. Their age ranged from 25 to 73 years old (mean: 39.33). Three cases (20%) recurred twice and the other 12 patients (80%) recurred once. All patients underwent excision of the mass and submandibular gland (except 2 cases who had undergone excision of the submandibular gland in previous surgery), and the pathological results were recurrent pleomorphic adenoma, with multi-nodules and incomplete capsule. The follow-up period was 1-13 years (median: 6) and only 1 patient (6.67%) suffered from suspected recurrence, who didn't receive second surgery due to his old age. CONCLUSIONS: Recurrent pleomorphic adenoma in the submandibular gland is rare. Its clinical and pathological features were similar to those of the primary pleomorphic adenoma and surgical treatment is effective.
