Abstract
The use of fine needle aspiration (FNA) cytology was reviewed in 117 cases of soft-tissue lesions: 23 non-neoplastic lesions, 34 benign mesenchymal tumors and 60 histologically proven soft-tissue sarcomas. The soft-tissue sarcoma aspirates were classified according to their cytomorphology into five groups of possible histologic diagnoses. Difficulties were experienced in the correct assessment of aspirates from low-grade malignancies. On the other hand, in high-grade malignant sarcomas and in recurrent or metastatic soft-tissue sarcoma, FNA cytology was useful in both the initial diagnosis of a new lesion (22 patients) and in the confirmation or exclusion of a suspected treatment failure (38 patients with recurrence or metastases). In the latter, FNA cytology supported the clinical data and reduced the number of repeat open biopsies. However, the final diagnosis of soft-tissue sarcomas should be based upon the histologic study of tissue sections.
