Adenome pleomorphe a localisation extra-parotidienne

Objectives : Pleormorphic adenoma is a benign tumor of salivary gland. It mainly occurs in the parotid gland. The submandibular and minor salivary glands are rarely sites of occurrence. We describe the features of pleomorphic adenoma occurring at these sites. Material and methods: Between 2000 and 2009, 15 cases of pleomorphic adenoma occurring externly to the parotid have been collected. Results: Tumors were seen in the submandibular gland in 40 % of cases, in the hard palate in 33 % of cases, in the upper lip in 20 % of cases and in the parapharyngeal space in 7 % of cases. The mean age of patients was 48 years. The majority of cases were female. All patients were operated. We didn't report recurrence or malignants tumors after one year follow-up. Conclusion: After the parotid gland, the most common site of a pleomorphic adenoma is the submandibular gland followed by minor salivary gland of palate and lips. Each localisation has his clinical and therapeutic particularities.
