Tuberculous lymphadenitis is common in Central Africa, where diagnosis by histological examination of a biopsied node is often delayed. In the present study, the naked eye appearance of the cut surface of 306 consecutive biopsied lymph nodes was compared with the histological diagnosis. One hundred and eight-eight nodes showed tuberculosis on histology (including two with coexisting second pathology). One hundred and forty-eight (79%) cases of tuberculous lymphadenitis (including both with coexisting second pathology) showed noncaseating tuberculomata or caseation visible on naked eye examination. Such signs were not seen in other nodes. Other signs were seen in another 18 (10%) tuberculous nodes. It is concluded that naked eye examination of nodes provides useful information for the diagnosis of tuberculous lymphadenitis, pending confirmation by histology.
结核性淋巴结炎在中非很常见，在那里通过对活检淋巴结进行组织学检查来诊断往往会延迟。在本研究中，对306个连续活检淋巴结的切面肉眼外观与组织学诊断进行了比较。188个淋巴结在组织学上显示为结核（包括2个伴有并存的第二种病理情况）。148例（79%）结核性淋巴结炎病例（包括伴有并存的第二种病理情况的病例）在肉眼检查时可见非干酪样结核瘤或干酪样坏死。在其他淋巴结中未见到此类征象。在另外18个（10%）结核性淋巴结中可见其他征象。得出的结论是，在组织学确诊之前，对淋巴结进行肉眼检查可为结核性淋巴结炎的诊断提供有用信息。
