Abstract

Benign metastasizing pleomorphic adenoma is an extremely rare neoplasm, although the pleomorphic adenoma is the most common neoplasm affecting the salivary glands. Metastasis commonly develops many years after the excision of the primary tumor and is usually proceeded by local recurrences. This is a case of pleomorphic adenoma in the parotid gland without a local recurrence. We describe a case of metastasizing pleomorphic adenoma in a 69 year-old woman. The literature concerning the subject is reviewed. The treatment of choice for the metastatic pleomorphic adenoma appears to be complete surgical excision.
