Are mixed tumors benign or malignant?
Neoplasms with more than one cell type but arising from only one germ layer are called “mixed tumors“. The best example is the benign mixed tumor (also called pleomorphic adenoma) of salivary gland.
What is a benign mixed tumor?
Benign mixed tumour of the skin (chondroid syringoma) is an uncommon skin adnexal tumour, usually presenting as a slow growing solitary painless nodule. The morphological appearances are similar to those of a pleomorphic adenoma of the salivary gland.
What is mixed parotid tumor?
Pleomorphic adenoma (PA), also known as benign mixed tumor, is the most common salivary tumor, constituting up to two-thirds of all salivary gland neoplasms (1). Mostly, PA is located in the parotid glands (85%), minor salivary glands (10%), and the submandibular glands (5%) (2).
Are large tumors usually cancerous?
Not all tumors are malignant, or cancerous, and not all are aggressive. There is no such thing as a good tumor. These masses of mutated and dysfunctional cells may cause pain and disfigurement, invade organs and, potentially, spread throughout the body.

Are adenomas always benign?
Adenomas are generally benign or non cancerous but carry the potential to become adenocarcinomas which are malignant or cancerous. As benign growths they can grow in size to press upon the surrounding vital structures and leading to severe consequences.
Do benign parotid tumors have to be removed?
Treatment of Salivary Gland Tumors
If you have a benign tumor, your doctor may recommend surgical removal to prevent it from becoming malignant over time. A benign tumor in the parotid gland can be removed using a surgical procedure called a partial superficial parotidectomy.
What is the most common parotid tumor?
Mucoepidermoid carcinomas are the most common type of salivary gland cancer. Most start in the parotid glands. They develop less often in the submandibular glands or in minor salivary glands inside the mouth. These cancers are usually low grade, but they can also be intermediate or high grade.
