Fourteen of 55 patients with non-Hodgkin's lymphomas demonstrating abdominal extranodal focal lesions at ultrasonographic (US) examination, ordered for clinical staging, underwent percutaneous ultrasonically guided, fine needle aspiration biopsy (FNAB) for pathological staging. The puncture was performed using a transperitoneal approach guided by a dynamic scanner. A correct cytological diagnosis was obtained in this manner in 13 patients (92%). Of these, 11 had true positive results and were classified as being in advanced pathological stage (four patients in IV, six in III S and one in III E). Two patients had true negative results and were in stage II. Only one patient had a false negative result. No false positive diagnoses were made. There were no complications related to the procedure. The data suggests that guided fine needle biopsy should be regarded as a safe, simple, and useful method of study in pathological staging of non-Hodgkin's lymphomas.
