Pleomorphic adenoma is a benign tumor commonly found in the salivary glands, particularly the parotid gland. It consists of a mix of glandular and connective tissue, and while slow-growing, it can cause swelling and discomfort. Surgical removal is the typical treatment.

A parotid tumor is an abnormal growth that develops in the parotid gland, the largest of the salivary glands, located near the jaw and in front of the ears. While most parotid tumors are benign, some can be malignant and require prompt medical attention.
