Pleomorphic adenoma
T2-weighted axial MRI: There is a sharply demarcated, hyperintense, partially lobulated mass arising from the left retromandibular fossa, filling the entire left parapharyngeal space. The lesion is surrounded by a hypointense capsule. This finding is a pleomorphic adenoma. Differential diagnoses include other tumors of the parotid gland.
Pleomorphic adenoma
Oral cavity of a patient, ventral view: A protrusion of the left lateral wall of the pharynx can be seen. Further diagnostics performed on the patient confirmed a pleomorphic adenoma of the parotid gland, which expanded into the parapharyngeal space.
Pleomorphic adenoma of the parotid gland
Photomicrograph of parotid gland tissue (H&E stain)
On the left, there is a hypercellular area made up of round epithelial cells with hyperchromatic nuclei and narrow, spindle-shaped myoepithelial cells with flattened nuclei. On the right, there is a paucicellular area predominantly made up of hyalinized stroma (pink acellular material).
This mixed pattern of epithelial (epithelial and myoepithelial cells) and mesenchymal (stroma) components within a salivary gland tumor is pathognomonic for pleomorphic adenoma.
