A Case of Minor Salivary Gland Pleomorphic Adenoma Arising from Larynx / 대한이비인후과학회지

ABSTRACT

Even though pleomorphic adenoma is the most common benign tumor of the major salivary gland, such as the parotid gland, it is relatively rare in the minor salivary gland since it accounts for only 10% of all reported pleomorphic adenoma. The minor salivary gland spreads throughout the oral cavity from nasopharynx, oropharynx, to larynx, and pleomorphic adenoma can be possibly found in every one of them. However, pleomorphic adenoma of the larynx is very rare. We experienced a case of 59 year old woman who presented 3 months history of voice change, swallowing difficulty. She had huge pleomorphic adenoma originated from arytenoid area of larynx. We resected the mass by suprahyoid approach and obtained good postoperative results. We reporte this case with a review of literature.
