title: Synchronous ipsilateral sebaceous lymphadenoma and acinic cell adenocarcinoma of the parotid gland.
abstract: The synchronous or metachronous occurrence of 2 tumors of the salivary glands in a patient is rare. These tumors are usually benign and of the same histologic type. Here we report a 78-year-old woman who developed a sebaceous lymphadenoma and an acinic cell adenocarcinoma simultaneously in the left parotid gland. To our knowledge, this combination of neoplasms has not been reported before.
