case_images: The posteroanterior chest roentgenogram showed a homogeneous opacity occupying the totality of left thoracic field with the presence of signs of mediastinal discharge in the right side (Figure 1).

case_images: The thoracic CT showed a mediastino pulmonary process localized at the left lobe superior measuring 104 * 102 * 141 mm comes in contact with the artery under Clavier and the left lateral edge of the aorta and surrounded the left branch of the pulmonary artery which stayed permeably associated with pleurisy ipsilateral of high abundance (Figure 2).
case_images: Histologically, (a) the tumor showed spindle-shaped cells forming sheets (Hematoxylin Eosin GX10), (b) the spindle cells are of uniform appearance with oval, dark-staining nuclei and scanty amount of indistinct cytoplasm (Hematoxylin Eosin GX20), and (c) we noted a myxoid pattern (Hematoxylin Eosin GX10).
