Overview
Pleomorphic adenoma is a benign neoplastic tumour of the salivary glands. It is the most common type of salivary gland tumour and the most common tumour of the parotid gland. It derives its name from the architectural pleomorphism (variable appearance) seen by light microscopy. It is also known as "Mixed tumor, salivary gland type", which describes its pleomorphic appearance as opposed to its dual origin from epithelial and myoepithelial elements.[1]
Ultrasound
In terms of imaging studies, ultrasound can determine and characterize superficial parotid tumors. Certain types of salivary gland tumors have certain sonographic characteristics on ultrasound[2]. Ultrasound is also frequently used to guide FNA or core needle biopsy.
- At Ultrasound, pleomorphic adenomas are hypoechoic, well-defined, lobulated tumors with posterior acoustic enhancement and may contain calcifications.
