Abstract
Percutaneous fine needle aspiration biopsy of retroperitoneal lymph nodes and abdomonal masses was performed in 109 patients. Eighty-five per cent of the aspiration biopsies yielded sufficient cytologic material for a correct diagnosis of carcinoma or lymphoma. Indications include confirmation of lymphangiographic findings and the establishment of a histologic diagnosis in lieu of surgery. No significant complications were encountered.
