From 1980 to 1991, 808 aspiration cytology specimens ofsuperficial lymph nodes were obtained from 740 patients. In228 of the 740 patients, the results of aspiration cytology werecompared with the histological diagnosis made on subsequent surgical biopsy. Of 110 cases of metastatic tumor, 99 (90%) were cytologically diagnosed as metastatic tumor, and 1 (1%) as malignant lymphoma. Of 72 cases of malignant lymphoma, 53 (74%) were cytologically diagnosed as malignant lymphoma, and 1 (1%) as metastatic tumor. Of 46 cases of reactive disease, 2 (4%) were considered to be false for malignant lymphoma. Malignant lymphoma was classified into 3 groups: B cell lymphoma, T cell lymphoma and Hodgkin's disease. The rate of positive cytologic diagnosis for malignancy was 87%(40 of 46) for B cell lymphoma, 50%(10 of 20) for T cell lymphoma and 67%(4 of 6) for Hodgkin's disease. T cell lymphomas were subclassified by the malignancy grade using the updated kiel classification. The positive diagnosis rate was 86%(6 of 7) for the high grade group and 31%(4 of 13) for the low grade group.
