Development of pyothorax-associated pleural lymphoma in relation to focal cytokinemic condition and Epstein-Barr virus infection.
We report an initial case of pyothorax-associated pleural lymphoma (PAPL) in which the level of interleukin 6 (IL-6) was remarkably high in the pleural fluid contaminated with tumor cells; at the same time Epstein-Barr virus (EBV)-encoded small RNAs (EBERs) were detected in the lymphoma cells by in situ hybridization. These findings suggest the possibility that EBV-transformed B cells proliferated in the focal cytokinemic condition caused by long-standing chronic inflammation of the pleura and give us a clue to the lymphoma genesis of PAPL.
