What is a nodule in the parotid gland?
Parotid tumors are abnormal growths of cells (tumors) that form in the parotid glands. The parotid glands are two salivary glands that sit just in front of the ears on each side of the face. Salivary glands produce saliva to aid in chewing and digesting food.
What is the most common benign tumor seen in parotid gland?
Most salivary tumors grow in the parotid gland. Pleomorphic adenomas are the most common parotid tumor. It grows slowly and is benign. A pleomorphic adenoma begins as a painless lump at the back of the jaw, just below the earlobe.
What does hypoechoic parotid nodules mean?
In acute inflammation, salivary glands are enlarged and hypoechoic with increased blood flow; they may contain multiple small, oval, hypoechoic areas. In chronic inflammation, salivary glands are normal sized or smaller, hypoechoic, and inhomogeneous.
What is parotid enlargement?
Parotid enlargement (also known as parotidomegaly) has a wide differential given the significant breadth of pathology that can affect the parotid gland. These can be separated by the standard surgical sieve approach into infective, inflammatory, immune, neoplastic, infiltrative, and congenital causes.
Why do alcoholics get parotid enlargement?
Parotid enlargement is frequently observed in heavy drinkers with and without chronic liver disease. A histologic study at necropsy demonstrated an increase in adipose tissue at the expense of acinar tissue in the salivary glands of patients with alcoholic cirrhosis compared with the control group.
Is there a nodule in the right parotid gland?

How are hypoechoic lesions determined on parotid gland ultrasound?
The presence of hypoechoic lesions within the parotid gland parenchyma was determined in each scan. Sjogren’s syndrome (SS) was diagnosed according to AECG or preliminary ACR criteria. Statistical analyses were performed using Fisher’s exact and Student’s t-test.
What kind of cancer is in the parotid gland?
Parotid tumors. While most parotid tumors are noncancerous (benign), the parotid glands are where nearly 25 percent of cancerous (malignant) salivary gland tumors develop. The parotid glands, located just in front of the ears on each side of the face, are the largest of the three sets of major salivary glands.
