Pathological findings were consistent with a diagnosis of lung-metastatic breast phyllodes tumor, and curative resection was achieved (Figure 5).
Computed tomography scan acquired 4 months after lung surgery showing (a) a 10 cm mass in the mediastinum (arrow) and (b) a 6 cm mass in the left thoracic cavity (arrow).
