中文摘要

EBV阳性原发结内T细胞/NK细胞淋巴瘤(TNKL)是一种罕见诊断,预后不良。其与滤泡性淋巴瘤(FL)、经典型霍奇金淋巴瘤(cHL)或其他非霍奇金淋巴瘤之间的关系尚未确立。我们描述了一例在既往FL背景下发生的EBV阳性cHL和EBV阳性原发结内TNKL,在一名免疫功能正常患者的单次淋巴结活检中同时发现全部3种亚型。强化一线治疗仅获得暂时缓解,随后迅速进展并伴有噬血细胞性淋巴组织细胞增生症(HLH)。我们讨论了这三种淋巴瘤亚型之间的关系,以及EBV和免疫失调作为这一此前未描述的复合淋巴瘤促成因素的潜在作用。

EBV-positive primary nodal T-cell/NK cell lymphoma (TNKL) is a rare diagnosis with a poor prognosis. No relationship with follicular lymphoma (FL), classic Hodgkin lymphoma (cHL), or other non-Hodgkin lymphomas is established.

We describe a case of Epstein-Barr virus (EBV)-positive cHL and EBV-positive primary nodal TNKL in the background of an antecedent FL, with all 3 subtypes identified in a single lymph node biopsy from an immunocompetent patient. Intensive frontline therapy achieved only a temporary response, with subsequent rapid progression associated with hemophagocytic lymphohistiocytosis (HLH).

We discuss the relationship of the three lymphoma subtypes and the potential roles of EBV and immune dysregulation as contributing factors to this previously undescribed composite lymphoma.
