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. 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. Treatment depends on the location and stage of the tumor. Treatment options may include surgery to remove the affected tissues, radiation therapy, and chemotherapy.
