渗出液中存在单一的小淋巴细胞可能由于慢性淋巴细胞白血病(CLL)、小细胞型恶性淋巴瘤(SLML)或慢性炎症过程如结核所致。本文表明,在这种富有淋巴细胞的胸水中,T 和B 淋巴细胞计数是可以酌量签别良、恶性渗出液的一种可靠方法。在10例非恶性疾病的胸水中T 淋巴细胞平均占80.2%,B 淋巴细胞平均占7.4%,明显相反;在伴有淋巴瘤或白血病患者的胸水中则以B 淋巴细胞为主(平均占83.3%)。因为慢性淋巴细胞型淋巴瘤和白血病大多起源于B 淋巴细胞,而很少起源于T 细胞,作者断定,富含B 细胞的渗出液,恶性可能性大。T 细胞的渗出液几乎总是良性。
The presence of a single small lymphocyte in the exudate may be due to chronic lymphocytic leukemia (CLL), small cell lymphoma (SLML) or chronic inflammatory processes such as tuberculosis. This article shows that T and B lymphocyte counts in this lymphoid pleural effusion are a reliable way to discreetly check for benign and malignant exudates. In 10 cases of non-malignant pleural effusion, T lymphocytes accounted for 80.2% of the average, B lymphocytes accounted for an average of 7.4%, in contrast; in patients with lymphoma or leukemia in pleural effusion is the main B lymphocytes (an average of 83.3 %). Because most chronic lymphocytic and leukemias originate in B lymphocytes and rarely originate from T cells, the authors conclude that exudates that are rich in B cells are highly likely to be malignant. T cell exudates are almost always benign.
