[Recurrent extensive pleomorphic adenoma (mixed tumor) of the submandibular gland--diagnosis and therapy].

The authors report an extensive recurrent pleomorphic adenoma of the submandibular gland with destruction of the ramus of the lower jaw. The advantages of computed tomography are the possibility of assessing the osseous structures, the extension of the soft parts, and the relation to the adjacent neck structures. Despite the unusual bone infiltration, histological examination did not point to malignancy.
