All procedures were performed on an outpatient basis. Patients with inconclusive findings or with a diagnosis of unaffected splenic tissue were followed up to discriminate between true and false-negative results.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>All procedures ended up with sampling of splenic tissue without severe complications requiring hospitalization or supportive countermeasures. None was interrupted because of adverse event (AE)s. Out of 44 samples, a final diagnosis was accomplished in 39 cases, with a diagnostic yield of 88.6%. A diagnosis of lymphoma was made in 22 cases. Other diagnoses included: splenic metastases and splenic sarcoma (3 cases each), non-neoplastic lesions (3 cases), and unaffected splenic tissue (8 cases). Among the latter 8 patients, 1 received a diagnosis of Hodgkin lymphoma by marrow biopsy. All the other 7 patients never received a diagnosis of neoplasm and were true negative. Among the 5 patients with insufficient sampling, 3 were never diagnosed with a neoplasm during follow-up; 1 had myelofibrosis and 1 angiosarcoma. The sensitivity of the procedure was 96.6%; specificity was 100% and accuracy was 86.4%.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n
