title: Fine needle aspiration cytology in the diagnosis of bone tumours.
abstract: Fine needle aspiration (FNA) cytology was performed on 62 primary and 22 metastatic bone tumours. Histological correlation was available in all 62 primary bone tumours, which included 7 benign and 53 malignant tumours. The most common of the malignant tumours were Ewing's sarcoma, followed by giant cell tumour, osteosarcoma and chondrosarcoma. The benign tumours included 4 enchondromas, 1 chondromyxoid fibroma and 2 osteochondromas. The overall cytodiagnostic accuracy in primary malignant bone tumours was 86.9%, the specificity was 100% and cytological categorization of tumours was possible in the majority of cases. This eliminated the need for bioptic confirmation. Our results indicate that FNA cytology is a valuable diagnostic tool in bone tumours.
