3D Printed Metastatic Tumour in Lung from Primary Testicular Cancer

3D Printed Metastatic Tumour in Lung from Primary Testicular Cancer Clinical HistoryA 37-year old male patient presents with a 1-month history of lethargy, cough and weight loss. He had a history of an orchiectomy 18 months previous for a testicular tumour. Then 12 months post-op he underwent neck radiotherapy to treat metastasis. On admission, he became acutely dyspnoeic and hypoxic and died. Pathology This right lung specimen (and portions of 4 ribs) has been sliced longitudinally. There are numerous rounded tumour nodules evident in the lung parenchyma ranging from 5 to 30mm in diameter. The tumours are variegated in appearance with pale yellow and dark brown cut surfaces. One tumour is extending along the bronchus of the lower lobe forming a cast. Several nodules project from the pleural surface and some show central umbilication from necrosis and haemorrhage. This is an example of pulmonary metastases from a mixed germ cell testicular tumour, most l
