case_images: Subsequently, contrast-enhanced computed tomography neck performd showed features of enlarged mediastinal necrotic nodes with likely metastatic multiple liver and lung lesions (Figure 2).
case_images: The tumour tissue shows neoplastic cells arranged in sheets. These cells are markedly pleomorphic with large, irregular vesicular nuclei and prominent large nucleoli. (H&E stain, 400x magnification).
