Primary effusion lymphoma (PEL) is a rare type of lymphoma that arises in the body cavity without detectable masses. It is associated with human herpes virus-8 (HHV-8), Epstein-Barr virus (EBV), and human immunodeficiency virus (HIV). Recently, PEL unrelated to viral infection has been reported and it has been termed HHV-8 unrelated primary effusion lymphoma-like lymphoma (HHV-8 unrelated PEL-like lymphoma). Here, we report a case of HHV-8 unrelated PEL-like lymphoma in an 80-year-old woman. Chest X-ray and computed tomography revealed left-sided pleural effusion. Pleural effusion analysis and mediastinoscopic biopsy showed atypical cells that had originated from the B cells. The cells were positive for CD20 and bcl-2, but negative for CD3, CD5, CD21, CD30, CD138, epithelial membrane antigen, and HHV-8. Serological tests for HIV and EBV were negative. Considering the patient's age, further treatments were not performed. She has shown good prognosis without chemotherapy for more than 18 months.
原发性渗出性淋巴瘤(PEL)是一种罕见的淋巴瘤类型,发生于体腔且无可检测到的肿块。它与人类疱疹病毒8型(HHV-8)、爱泼斯坦-巴尔病毒(EBV)和人类免疫缺陷病毒(HIV)有关。最近,有报道称存在与病毒感染无关的PEL,它被称为HHV-8无关的原发性渗出性淋巴瘤样淋巴瘤(HHV-8无关的PEL样淋巴瘤)。在此,我们报告一例80岁女性的HHV-8无关的PEL样淋巴瘤病例。胸部X线和计算机断层扫描显示左侧胸腔积液。胸腔积液分析和纵隔镜活检显示有起源于B细胞的非典型细胞。这些细胞CD20和bcl-2呈阳性,但CD3、CD5、CD21、CD30、CD138、上皮膜抗原和HHV-8呈阴性。HIV和EBV的血清学检测均为阴性。考虑到患者年龄,未进行进一步治疗。她在未接受化疗的情况下已显示出超过18个月的良好预后。
