Pleomorphic adenoma is also called a mixed tumor and it most commonly occurs in the salivary gland. This neoplasm has a low grade malignant potential, but it may also show aggressive clinical behavior like recurrence or metastasis. We report here on a case of a tumor that was confirmed to be primary pulmonary carcinoma ex-pleomorphic adenoma by the pathologic examination after complete resection, and it had the characteristics of malignant neoplasms, such as multiple metastases.
