Primary cutaneous Epstein-Barr virus-positive diffuse large B-cell lymphoma (PC-EBV-DLBCL) is a rare and aggressive neoplasm with a poorer prognosis than other cutaneous lymphoma. Here, we present the F-fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) scan findings of a 39-year-old male with erythematous ulcerative nodules, which showed a gamut of cutaneous lesions consistent with EBV-associated PC-DLBCL. We highlight the utility of F-FDG PET/CT in evaluating the extent of disease, involvement of extranodal sites, and response to treatment in PC-EBV-DLBCL.
原发性皮肤爱泼斯坦-巴尔病毒阳性弥漫性大B细胞淋巴瘤（PC-EBV-DLBCL）是一种罕见且侵袭性强的肿瘤，其预后比其他皮肤淋巴瘤更差。在此，我们展示了一名39岁男性红斑溃疡性结节患者的18F-氟脱氧葡萄糖（18F-FDG）正电子发射断层扫描/计算机断层扫描（PET/CT）结果，该结果显示一系列与EBV相关的PC-DLBCL一致的皮肤病变。我们强调了18F-FDG PET/CT在评估PC-EBV-DLBCL疾病范围、结外部位受累情况及治疗反应方面的作用。
