Proliferative sialometaplasia arising in an intraparotid lymph node

A case of florid proliferative sialometaplasia arising in salivary ductal inclusions in an intraparotid lymph node is described. This lesion probably represents an exuberant response to sialadenitis. Other entities that enter into its differential diagnosis in this particular location are discussed. Except for Warthin tumors, lesions of clinical import originating from such inclusions are rare.
