A 78-year-old woman was referred to this hospital because of exertional dyspnea for 2 weeks. Although she was treated with anti-tuberculous medication under the assumption that she had tuberculous pleuritis, her dyspnea continued. Physical examination revealed diminished breath sounds over the left lung field. Chest radiography showed a large left pleural effusion. The pleural effusion revealed malignant cell dominant exudates with a high adenosine deaminase level. Serological tests were negative for HIV. Computed tomography scan of the chest and abdomen showed pleural effusion, but no mass or pathological lymph nodes were detected. The biopsy specimen of the pleura was diagnosed as malignant B cell lymphoma with plasmacytoid features, suggesting a possibility of primary effusion lymphoma. Polymerase chain reaction assay of tumor was positive for HHV-8 DNA. She underwent pleurodesis during Video-Assisted Thoracic Surgery, and her dyspnea subsequently improved.
