由于免疫学、细胞化学和电镜研究的进展,恶性淋巴瘤的研究在二十余年来取得了很大的成绩。恶性淋巴瘤过去仅仅根据形态学分类,现在用免疫学和细胞化学方法,已能识别正常的T、B淋巴细胞及单核、组织细胞。应用这些方法研究恶性淋巴瘤已经明确它们是免疫系统的肿瘤。现在认为所有“结节性”淋巴瘤,均来自滤泡中心的B淋巴细胞。B淋巴细 Due to advances in immunology, cytochemistry, and electron microscopy, studies of malignant lymphoma have yielded great results in more than two decades. Malignant lymphomas were previously classified only by morphology. Now, immunological and cytochemical methods have been used to identify normal T and B lymphocytes and mononuclear and histiocytes. Using these methods to study malignant lymphomas has made it clear that they are tumors of the immune system. All “nodular” lymphomas are now considered to be from the center of the follicle B lymphocytes. B lymphatics
