ResumoCytological results of US-guided fine needle aspiration biopsies of enlarged lymph nodes from 179 patients were analyzed retrospectively. The final diagnoses were benign lymphadenopathy in 90 cases, metastasis in 56, and malignant lymphoma in 33 cases. The material was sufficient for cytological analysis in 174 cases (97.2%). Correct diagnosis of malignant (C IV—V) and benign (C I—II) lymphadenopathy in the whole material was possible in 80 percent of cases. Correct subtyping of lymphoma was possible in 63.6 percent of the cases. There was one (0.6%) false positive (C IV), 6 (8.5%) false negative (C I—II), and 24 (13.8%) suspicious (C III) cytological findings. All but one of the false negative cytological findings were from superficial lymph nodes. No complications occurred. US-guided lymph node aspiration biopsy is safe and accurate in the superficial, anterior mediastinal, abdominal, and retroperitoneal lymphonodal areas. Lymph nodes with a C 0 cytological result should undergo rebiopsy and suspicious (C III) or clinically doubtful cases should be referred for a surgical biopsy.
