Multifocal Occurrence of Warthin’s Tumor in Both Parotid Glands and in the Larynx

Abstract

The Warthin's tumor or papillary cystadenoma lymphomatosum is a benign neoplasm which affects commonly the salivary glands und especially the parotid gland. We present a case of an 80-year-old Caucasian woman, who presented in our ENT department because of a progressive swelling in the left parotid gland. The clinical as well as the radiological findings suggested a multifocal lobular neoplasia in both parotid glands as well as a tumor in the left morgagni sinus of the larynx, most probably of benign nature. We proceeded in performing a lateral parotidectomy of the left side, a fine needle aspiration of the right parotid tumor and a CO 2 laser assisted transoral excision of the larynx tumor. The histopathological examination showed a multifocal cystadenolymphoma of both parotid glands as well as the left supraglottic region (left laryngeal ventricle) with no signs of malignancy. To our knowledge, this is the first case described in the literature of a multifocal cystadenolymphoma of both parotid glands and the larynx.
