Fine needle, percutaneous aspiration of suspect lymph nodes was carried out in 29 patients during fluoroscopy. The correct positioning of the needle was assured if the node moved with the tip of the needle. In 29 patients, there were 65 successful aspirations and 29 failures. Anesthesia is recommended but care should be taken that the anesthetic does not reach the lymph node itself as this can cause distortion of the cells.
