Is teratoma a mixed tumor?

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. Neoplasms with more than one cell type and arising from more than one germ layer are called teratomas.

Do benign parotid tumors have to be removed?

Why pleomorphic adenoma is a mixed tumor?

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).
