感染人类免疫缺陷病毒的患者容易患上各种淋巴增生性疾病。在这些患者中,恶性淋巴瘤的临床表现常常与良性淋巴组织增生症重叠。两者都可能包括淋巴结病、脾肿大、血液和骨髓萎缩,以及富含淋巴细胞的积液。由于良性和恶性富含淋巴细胞的积液,以及其他恶性肿瘤的积液,可能含有类似免疫母细胞或Burkitt细胞的大细胞,仅凭细胞形态特征不能确定恶性淋巴瘤的诊断。通常使用B和T细胞标记物抗体的免疫分型板往往无法证明获得性免疫缺陷综合征(AIDS)患者淋巴瘤细胞的细胞谱系。当常规细胞标记物研究未能证明细胞谱系或克隆性时,作者使用基因重排来确认三名艾滋病患者积液中恶性淋巴瘤的诊断。生物素化探针的使用消除了处理放射性物质的需要,并使研究能够在常规免疫组织化学实验室进行。
Patients infected with human immunodeficiency virus are prone to a wide variety of lymphoproliferative disorders. In these patients the clinical presentation of malignant lymphoma often overlaps with that of benign lymphoid proliferations. Both may include lymphadenopathy, splenomegaly, blood and bone marrow dyscrasias, and lymphocyte-rich effusions. Because benign and malignant lymphocyte-rich effusions, as well as effusions from other malignancies, may contain large cells that resemble immunoblasts or Burkitt's cells, cytomorphologic characteristics alone are unreliable for definitive diagnosis of malignant lymphoma. Usual immunotyping panels using antibodies to B- and T-cell markers frequently fail to demonstrate cell lineage in lymphoma cells of patients with acquired immune deficiency syndrome (AIDS). The authors used gene rearrangement to confirm the diagnosis of malignant lymphoma in effusions from three patients with AIDS when routine cell marker studies failed to demonstrate cell lineage or clonality. Use of biotinylated probes eliminated the need for handling radioactive material and enabled performance of studies in a routine immunohistochemistry laboratory.
