title: Salivary gland anlage tumor. A case with widespread necrosis and large cyst formation.
abstract: We describe a case of the salivary gland anlage tumor (congenital pleomorphic adenoma). The tumor arose in the nasopharynx as a pedunculated mass. Microscopically most of the tumor contained large necrotic areas which revealed squamous cell metaplasia resulting in the formation of large cysts. This feature has never been described previously in this tumor and might lead to an erroneous diagnosis.
