[Standards and criteria in histologic intraoperative diagnosis in the lymph nodes].

Using frozen sections and classic paraffin sections of the lymph nodes, comparative diagnostic analysis was done in the patients with differently localized malignant tumours. The analysis was based on 86 patients with malignant tumours mostly localized in the maxillofacial region. The frozen sections diagnoses are divided into "metastasing carcinoma in the lymph node", "reactive lymphadenitis", "malignant", "benign", "malignant lymphoma" and "normal lymph node". Diagnostic reproducibility on the level of 90% cases using classic sections was estimated. Negative results in 10% were discussed and some recommendations for improvement of the 9:1 relation were done.
