Abstract

A 58-year-old male patient presented with a recurrent true malignant mixed tumor of the parotid gland. Patchy pulmonary opacities were identified with a chest radiograph. Subsequently, a CT scan of the chest showed pulmonary parenchymal consolidation with amorphous calcifications. This abnormality was confirmed to be the result of a metastatic true malignant mixed tumor by using CT-guided biopsy. The current case demonstrated an extremely rare example of atypical pulmonary metastases from a true malignant mixed tumor of the parotid gland showing an air-space pattern and calcification.
