(1) for their interesting article on a case of atypical pulmonary metastases from carcinosarcoma of the parotid gland, demonstrating the radiologic features of an air-space pattern and calcification. We concur with their study in considering this type of lesions a formidable diagnostic challenge in the patients with unknown extrapulmonary malignancies. We would like to lend more support to this study by offering our experience with a similar exceptional case of atypical pulmonary metastases from a different kind of primary tumor.
