A Case of Dumbbell Shaped Parotid Warthin’s Tumor Extending to the Parapharyngeal Space

Abstract

We report a case of dumbbell-shaped Warthin’s tumor extending from the parotid gland to the parapharyngeal space. A 64-year-old man was referred because of a left neck tumor and a feeling of dysphagia. CT scanning and an MRI examination revealed a tumor with clear boundaries extending from the deep lobe of the parotid gland into the parapharyngeal space. Warthin’s tumor was diagnosed based on a biopsy from the oral cavity, and a transcervical-parotid approach was chosen. The tumor size was approximately 9 cm, but the tumor was relatively soft with minimal adhesion; thus, we were able to remove it en bloc without any major complications. The patient exhibited first bite syndrome on the eighth day after surgery, but the pain gradually disappeared.
