There is relatively little information concerning the use of fine‐needle aspiration (FNA) to diagnose extranodal and extramedullary hematopoietic malignancies. Seventy‐one such cases diagnosed by FNA form the basis of this study. Seventy‐one cases of FNAs performed between 1988 and 1998 on extranodal and extramedullary hematopoietic malignancies were reviewed in order to evaluate the usefulness of this technique in diagnosing these entities as well as to assess patterns of relapse. There were 45 male and 26 female patients ranging in age from 29–86 years (mean, 68 years). Sixty‐six patients had a previous history of a hematopoietic malignancy. Aspirates from 65 of these patients were consistent with the patient's known primary. One aspirate of a paravertebral mass from a multiple myeloma patient showed extramedullary hematopoiesis. The remaining five aspirates were cases of multiple myeloma that first presented as soft tissue masses. The most common malignancies were lymphoma: 52 cases (73%), 48 large cell lymphomas, four mixed small and large cell lymphoma; followed by multiple myeloma: 12 cases (17%); leukemia: four cases (5.4%); Hodgkin disease: two cases (2.8%); and one case of extramedullary hematopoiesis. The aspirate sites were soft tissue: 23 cases (32%); bone: 17 cases (24%); kidney: 14 cases (20%); liver: 11 cases (15%); lung: three cases (4%); adrenal: two cases (3%); and eye: one case. The interval between primary diagnosis and FNA was 1–36 months (mean, 13 months). In conclusion, 98% of the aspirates were neoplastic in patients with a known history of hematopoietic malignancies. The most common site of involvement was soft tissue in 23 (32%) cases. In five patients with multiple myeloma, the FNA diagnosis prompted a work‐up to find the primary site of involvement. FNA is a useful technique in assessing extranodal and extramedullary hematopoietic malignancies. Diagn. Cytopathol. 2000;23:318–321. © 2000 Wiley‐Liss, Inc.
