title: Fine needle aspiration biopsy of retroperitoneal lymph nodes and abdominal masses: an updated report.
abstract: Percutaneous fine needle aspiration biopsy of retroperitoneal lymph nodes and abdominal masses was performed in 109 patients. Eighty-five per cent of the aspiration biopsies yielded sufficient cytologic material for a correct diagnosis. Indications include confirmation of lymphangiographic findings and the establishment of a histologic diagnosis in lieu of surgery. No significant complications were encountered.
