淋巴结单纯性窦扩张的病理诊断意义

Pathological Significance of the Simple Sinus Dilation of Lymph Node

目的 进一步探讨淋巴结单纯性窦扩张 (SSD)的病理诊断意义。方法 观察 770例 3类 4种已知背景性病变淋巴结的SSD检出情况 ,分析淋巴结这几种背景性病变呈现SSD的检出率 ;还分析了 8例SSD淋巴结背景性病变的分布特点。结果 ① 770例淋巴结有 4例呈现轻度SSD(5 .2‰ ) ,其中非霍奇金淋巴瘤、霍奇金淋巴瘤、转移癌和反应性增生的SSD检出率依序分别为 3% (3 10 0 ) ,0 ,0 .2 % (1 5 0 0 )和 0 ;②已发现的 8例 (本文 4例和前文 4例〔1〕)淋巴结SSD的背景性病变皆为恶性肿瘤 :主要为非霍奇金淋巴瘤 (5例 ) ,其次为转移癌 (3例 )。结论 对于呈现SSD的淋巴结 (尤其是显著者 ) ,应注意观察其中是否存在恶性病变 (首先是非霍奇金淋巴瘤 )

Objective To explore the pathologic diagnostic significance of the simple sinus dilation(SSD) in lymph nodes. Methods Frequency and detection rate of SSD were investigated in 770 cases of lymphnode lesion with a variety of underlying diseases.Pathological features were also analyzed in 8 cases of SSD. Results There were 4 cases of SSD found in 770 cases of lymphnode lesion involved in non Hodgkin's lymphoma and metastatic carcinoma.All the 8 cases had underlain malignant diseases,including non Hodgkin's lymphoma(5 cases) and metastatic carcinomas(3 cases). Conclusion Appearance of SSD in lymph nodes suggests that there may be malignant tumors underneath
