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.
