Pleomorphic adenoma is the most common benign salivary gland neoplasm (%75-80). It is found mostly in the parotid gland in middle-aged
women. The optimal treatment is superficial or total parotidectomy with facial nerve preservation, which results in local control rates of 95%
or higher. Radiotherapy (RT) is indicated for ositive margins, unresectable tumours, and multifocal recurrences after prior resection. Local
control rates after RT for microscopic and gross residual tumour are approximately 80% to 85% and 40% to 60%, respectively. In this
article, we share our experience of 2 cases of recurrent pleomorphic adenoma.
