An atypically located pleomorphic adenoma: Radiological and pathological correlation

J Med Imaging Radiat Oncol. 2022 Feb;66(1):105-106. doi: 10.1111/1754-9485.13178. Epub 2021 Mar 25.


Pleomorphic adenoma is a common benign salivary gland neoplasm which very rarely occurs in the breast. Its radiologic and pathologic appearance may be mistaken for other benign or malignant lesions such as a fibroadenoma or invasive ductal carcinoma. Due to the risk of local recurrence and, rarely, malignant transformation, wide local excision with clear margins is recommended. As such, a correct diagnosis of this lesion is important to ensure appropriate surgical treatment. We report a case of an atypically located pleomorphic adenoma with radiologic-pathologic correlation in an asymptomatic 63-year-old woman.
