Primary effusion lymphoma (PEL) is a subtype of non-Hodgkin lymphoma that presents as serous effusions without detectable masses or organomegaly. Here we report a case of PEL-like lymphoma in a patient with past asbestos exposure. A 65-year-old man was referred to our hospital due to dyspnea upon exertion. He had been exposed to asbestos for three years in the construction industry. Chest X-ray and CT images demonstrated left pleural effusion. Cytological analysis of the pleural effusion revealed large atypical lymphocytes with distinct nuclear bodies and high nucleus-to-cytoplasm ratio. Immunohistochemical analyses showed that the cells were CD20(+), CD3(-), CD5(-), and CD10(-). These findings led to a diagnosis of diffuse large B-cell lymphoma. PEL or PEL-like lymphoma should be considered a potential cause of pleural effusion in subjects with past asbestos exposure.
原发性渗出性淋巴瘤（PEL）是非霍奇金淋巴瘤的一种亚型，表现为浆液性渗出液，无可检测到的肿块或器官肿大。在此，我们报告一例既往有石棉接触史患者的PEL样淋巴瘤病例。一名65岁男性因劳力性呼吸困难转诊至我院。他曾在建筑行业接触石棉三年。胸部X线和CT图像显示左侧胸腔积液。胸腔积液的细胞学分析显示有大的非典型淋巴细胞，具有明显的核体和高核质比。免疫组化分析显示细胞CD20(+)、CD3(-)、CD5(-)和CD10(-)。这些发现导致诊断为弥漫性大B细胞淋巴瘤。对于既往有石棉接触史的患者，应考虑PEL或PEL样淋巴瘤是胸腔积液的潜在原因。
