Overview

Tumors of the salivary glands (salivary gland neoplasm) may occur. These are usually benign, but may be malignant.

The most common type of benign tumor is pleomorphic adenoma, followed by Warthin's tumor.

The most common malignant tumor is mucoepidermoid carcinoma.

Eighty percent begin in the parotid gland.[1]

  • SALIVARY GLANDS: MIXED TUMOR OF PAROTID. The pre-auricular mass had enlarged to this size over a period of 5 years.(Courtesy of Dr. Charles E. Tomich, Indianapolis, IN.)

  • SALIVARY GLANDS: RECURRENT MIXED TUMOR. The characteristic multinodular growth of recurrent mixed tumor is obvious inthis parotid mass. (Courtesy of Dr. Lewis R. Eversole, Los Angeles, CA.)

  • SALIVARY GLANDS: MIXED TUMOR OF PALATE. Most mixed tumors involve only one side of the palate because there are few minor glands in the midline. In this case the tumor appears symmetrical on either side of the midline. Large intraoral tumors are susceptible to trauma-related ulceration, as illustrated here. (Courtesy of F. J.Kratochvil, Bethesda, MD.)

  • SALIVARY GLANDS: CANALICULAR ADENOMA. The upper lip is the site for over 70% of canalicular adenomas.

  • SALIVARY GLANDS: MUCOEPIDERMOID CARCINOMA OF PALATE. These tumors frequently are slightly raised, fluctuant, bluish discolorations of the palatal mucosa that are clinically thought to represent mucous escapereactions.

  • SALIVARY GLANDS: ACINIC CELL ADENOCARCINOMA: CLINICAL PRESENTATION: A 2.0-cm raised subcutaneous nodule just anterior to the lower portion of the ear is a common clinical presentation for acinic cell adenocarcinoma. The tumor is in the superficial lobe of the left parotid gland of this 24-year-old man.

  • SALIVARY GLANDS: ADENOID CYSTIC CARCINOMA. This sublingual gland tumor slowly enlarged to produce a large, lobulated mass in the anterior floor of the mouth. The oral mucosa is intact.

  • SALIVARY GLANDS: POLYMORPHOUS LOW-GRADE ADENOCARCINOMA. This tumor presented as a well-circumscribed, slow growing mass at the junction of the hard and soft palates. Pronounced telangiectasia of the overlying mucosa is evident. (Courtesy of Dr. Richard Canaan, Ocean Springs,MS.)

  • SALIVARY GLANDS: NECROTIZING SIALOMETAPLASIA. Swelling, as shown in this photograph of a palatal lesion, is a frequent initial clinical presentation. Many of the swellings subsequently ulcerate. (Courtesy of Dr. Ralph Correll, LosAngeles, CA.)
