Abstract:
A patient with sarcoidosis was found to have a massive left pleural effusion. Her chest computed tomography showed small nodules in the lung parenchyma and swelling of the hilar lymph nodes, with normal visceral and parietal pleura. Thoracoscopy showed white nodules on the visceral pleura and normal parietal pleura, which were resected. Epithelioid granulomas were seen in the visceral pleura and lung parenchyma. Surprisingly, in the parietal pleura, abnormal cells that were positive for the leukocyte common antigen, CD20, and CD79a were found, leading to the diagnosis of malignant B-cell lymphoma.
