Atypical pulmonary metastases from a true malignant mixed tumor of the parotid gland.

Lin WC, Li CS, Lin CK, Hsu HH, Chang TH, Chen TY, Huang GS - Korean J Radiol (2009)

Bottom Line: 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.

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.

Figure 1: 58-year-old male patient with true malignant mixed tumor of parotid gland metastasizing to lung.

Mentions: During this hospitalization, a chest radiograph indicated the presence of patchy opacities in his left lower lung field (Fig. 1A) not seen in previous chest radiographs; this warranted a CT scan for further characterization. A CT scan of the chest showed parenchymal consolidation with some amorphous calcifications (Fig. 1B); hence, the possibilities of fungal infection or granulomatous disease were considered initially. This patient had no fever and did not report associated symptoms of infectious or inflammatory respiratory tract diseases; therefore, a CT-guided biopsy of the pulmonary lesion was performed because of the concern of atypical pulmonary metastases. The biopsy generated two pieces of specimen that were used for histopathologic examination.
