Fine needle aspiration cytology of primary bone lesions.
Fine needle aspiration (FNA) cytologic findings were compared with the results of conventional histology in a series of primary bone lesions to determine the diagnostic accuracy of FNA cytology. The series included 12 osteogenic sarcomas, 4 Ewing's sarcomas, 3 chordomas, 3 myelomas, 2 chondrosarcomas, 2 undifferentiated sarcomas and 1 case each of normal bone and marrow elements, lymphoma and giant-cell tumor. All aspirates yielded adequate material for smear diagnosis, and all 29 cases were correctly identified as benign or malignant by cytology. In 19 cases (66%), specific cytologic diagnoses were rendered and histologically confirmed. This series is compared with other published series of bone aspirations in terms of technique, accuracy and ability to obtain diagnostic material. The importance of technique, radiographic investigations and experience in performing the aspirations in achieving a high diagnostic yield is emphasized.
