Examples include: Pleomorphic [Pleomorphism: variability in the size and shape of cells and/or their nuclei. Pleomorphism (microbiology): the ability of some bacteria to alter their shape or size in response to environmental conditions] adenoma of Parotid gland [either of a pair of large salivary glands situated just in front of each ear]. It contains neoplastic cells of epithelial origin and cartilage. Both of these different morphological structures are however derived from the same germ layer.
