电镜在淋巴瘤鉴别诊断中的价值

对疑为淋巴瘤而确诊有困难的４７例病理标本进行电镜检查，并逐一比较光、电镜的诊断结果，探讨电镜下淋巴瘤和非淋巴瘤的鉴别要点，以及淋巴瘤各亚型的特点。结果光镜下疑为横纹肌肉瘤、未分化癌及恶性肉芽肿的４例患者，电镜下均诊断为淋巴瘤，不同亚型的淋巴瘤在电镜下有不同的特点。提示电镜在淋巴瘤的鉴别诊断和分型中具有一定价值。

The Role of Electron Microscopy in the Differential Diagnosis of Lymphoma

Forty-seven tissue samples which were difficult to diagnose by light microscopy(LM) were examined by electron microscopy(EM) from 1984 to 1990 in the PLA's General Hospital,aiming at comparing the diagnostic results of CM and EM. The differential diagnosis of non-differentiated small cell tumors was very hard in route pathological-examination, but they all had the charateristics of their own,being helpful for differential diagnosis. However,there was no any detail report for the differential diagnosis of lymphomas by EM in China.We analyzed the results of lymphomas. Of the 47 cases of lymphomas examined by EM,there were 32 cases of non-Hodgkins lymphoma, 2 cases of histiocytic hyperplasia and lymphocytic leukemia each, and 1 case of malignant histiocytic hyperplasia, lymphomatous granuloma and histocytic reactive hyperplasia of bone marrow each. These results show that EM is helpful for the differential diagnosis of small cell tumors.
