Recurrent Pleomorphic Adenoma: a Case Report

摘要

Salivary gland tumors are rare, comprising less than 3% of all neoplasia of the head and neck region. Pleomorphic adenoma, also known as benign mixed tumor is the most common tumor of the salivary gland accounting for 60-80% of the benign variety. The tumor is almost always solitary and is usually found as a firm, mobile, painless slow growing mass. Multiple or bilateral pleomorphic adenomas are rare. After surgical resection, up to 43% of patients are at risk of recurrence, even as late as 45 years after the initial surgery. Here we report a case of recurrent pleomorphic adenoma in a 34-year-old male patient on the right side.
