Human herpes virus 8-negative effusion-based lymphoma. (A) A chest computed tomography scan reveals a large amount of pleural effusion. Pleural enhancement is characteristically observed on both sides of the chest. Mediastinal lymphadenopathy is also observed. Massive ascites with multiple lymphadenopathy is sometimes detected. (B, C) The effusion contains large pleomorphic cells with large blastic nuclei (Giemsa stain). Tumor cells are large, immunoblastic or plasmablastic (D), and express the B-cell-associated antigen CD20 (E). | Kim, Y., Park, C. J., Roh, J., & Huh, J. (2014).
