Chest X-ray of Case 2 shows an abnormal cardiomediastinal silhouette caused by a large left-sided mediastinal mass extending within the superior hemithorax medially. In addition, large left-sided pleural effusion is present, and several nodular opacities are noted in the left lung

Chest CT of Case 1 reveals a 13.7 × 9.2-cm superior mediastinal mass, multiple left pleural masses ranging from 2.4–2.7 cm, a 1.6-cm left upper lobe lung nodule, and bilateral pleural effusions

Pathologic examination of Case 1 shows varying degrees of compartmentalizing fibrosis associated with lymphocytic infiltrate. The infiltrating cells are mostly large with irregular and convoluted vesicular nuclei, 1–3 visible nucleoli, and moderate cytoplasm. The tumor cells are strongly positive for CD20. EBER in situ hybridization is positive in approximately 30% of the tumor cells

Microscopic sections of Case 2 show dense lymphoid infiltrate composed of large lymphoid cells with abundant pale cytoplasm, pleomorphic nuclei which form clusters and rounded nests surrounded by delicate fibrous bands. Frequent mitoses, including atypical mitotic forms are present. By immunohistochemistry, the tumor cells are positive for CD20, CD30, and Bcl-6. EBER in situ hybridization was negative
