title: Recurrent pleomorphic adenoma of the parotid gland involving the osseous external auditory canal. With a note on the foramen of Huschke.
abstract: A recurrence of a parotid pleomorphic adenoma presenting as an external ear canal mass is reported. The route of extension was radiographically documented as an incompletely closed foramen of Huschke. The historical and developmental features of this foramen and the mechanisms of tumor extension as they relate to it are discussed.
