Disease Overview

Myoepithelial carcinoma is a rare malignant (cancerous) tumor that usually occurs in the salivary glands in the mouth, but can also occur in skin and soft tissues. Approximately 66% of these tumors occur in a part of the salivary gland, known as the parotid gland. The average age of diagnosis is 55 years. Symptoms of myoepithelial carcinoma usually begin with a painless mass.[1051] Other symptoms vary depending on the site of the tumor and may include: hoarseness, nasal blockage, bleeding from the nose, pain, headaches, and facial weakness and paralysis.[12617] Treatment depends on the location and stage of the tumor. Treatment options may include surgery to remove the affected tissues, radiation therapy, and chemotherapy.[1051]
