case_images: Chest tomography (CT) scan revealed a voluminous right paramedian mass measuring 170 mm of diameter, with significant central calcification and infiltration of the pulmonary aorta and left pulmonary parenchyme; the left subclavicular lymphe nodes measuring 25 mm and a medium pericardial effusion were also found (Figure 1, Figure 2).The biopsy of the cervical lymph node revealed a poorly differentiated malignant tumor corresponding to a non-teratomatous germ cell tumor of yolk sac type, the immunohistochemistry confirmed the histological diagnosis with positive staining on PALP, AFP and pancytokeratine antibodies.
