title: Adenocarcinoma arising in warthin tumor of the parotid gland.
abstract: Warthin tumor is a well-defined benign salivary gland neoplasm consisting of     both epithelial and lymphoid components. The tumor is the second most common     benign tumor next to pleomorphic adenoma. We present a case of adenocarcinoma,     not otherwise classified, arising in unilateral Warthin tumor of the parotid     gland in a 63-year-old male patient. Carcinomas arising in or from the     epithelial component of a preexisting parotid Warthin tumor are rare and     differential diagnosis of metastasis from an adenocarcinoma in Warthin tumor is     important. The patient underwent a complete and thorough work-up, and no other     primary malignant lesion was found. No other primary malignant lesion had     manifested at the last one year follow-up period.
