| Abstract: | The fine needle aspiration cytomorphology and the number of lymphohistiocytic aggregates were correlated with five categories of benign lymph node histologies. Of 187 patients who had benign lymph node aspiration diagnoses made from 1975 to 1982 at the Medical College of Virginia, 26 had a subsequent lymph node biopsy. Excluded from the study were four cases with the biopsy site different from the aspiration site, three cases with evidence of metastatic carcinoma and one case of fistula at the site of biopsy. Of the remaining 18 cases, 13 (72%) had lymphohistiocytic aggregates on the aspiration slides. The mean number of lymphohistiocytic aggregates on the aspiration slides was greater in cases with histologic evidence of follicular hyperplasia (6.1) than in those with some other predominating benign histology (1.6). |
