Use of fine‐needle aspiration biopsy in the evaluation of splenic lesions in a cancer center
1997
Fine-needle aspiration biopsy (FNAB) of the spleen was performed on 50 patients, of whom 40 had had a previous diagnosis of malignancy (23 lymphoproliferative disorders, 13 carcinomas, 3 melanomas, and 1 sarcoma). The cytologic diagnoses included 22 cases positive for malignancy (10 lymphomas, 9 metastatic carcinomas, 2 metastatic melanomas, and 1 sarcoma), 18 cases negative for malignancy, 4 cases suspicious for malignancy, and 6 nondiagnostic specimens. No major complications were associated with the FNAB procedure; however, one patient did develop a pneumothorax that resolved spontaneously. Subsequent splenectomy was performed in 10 of the 50 cases. There were no false-positive diagnoses, and only one false-negative diagnosis, which was attributed to sampling error. The aspirate, showing only benign splenic parenchyma, was from a patient with splenomegaly and no previous diagnosis; subsequent splenectomy showed acute myelogenous leukemia. In our study, FNAB proved to be a safe and valuable diagnostic tool for evaluating splenic lesions in oncologic patients. Diagn. Cytopathol. 16:312–316, 1997. © 1997 Wiley-Liss, Inc.
