Pleomorphic adenoma arises commonly in the palate, and most lesions are within 30 mm. We report the case of a large pleomorphic adenoma arising in the palate. An 83-year-old woman presented to our department because of an eating disorder and snoring noticed by her family in July 2006. She had dementia, and her voice faded away as she spoke in daily life. Clinical examination revealed a 60-mm elastic-soft mass in the palate. The overlying mucosa was normal, except for a 14 × 20 mm ulcer. There was no induration around the tumor, and the tumor was movable. The cytodiagnosis was class II. In September 2006, tumor resection was performed with the patient under general anesthesia for a clinical diagnosis of pleomorphic adenoma. The tumor did not closely adhere to the surrounding tissue. The excised specimen measured 52 × 32 × 37 mm and was histopathologically diagnosed to be a pleomorphic ademona. The postoperative course was uneventful; snoring disappeared and feeding improved. Two years after surgery, there has been no evidence of recurrence.
