Abstract:
Pleomorphic adenoma (PA) is by far the most common salivary gland tumor. It is well known that PA can undergo malignant transformation. However, in rare occasions it can metastasize preserving its benign phenotype. Metastasizing pleomorphic adenoma (MPA) constitutes an extremely rare tumor. Here we are reporting an unusual MPA affecting the mandible that was preceded by a submandibular gland pleomorphic adenoma.
