  • Title: Fine needle aspiration cytology in the diagnosis of bone tumours.
    Author: Jayaram G, Gupta M.
    Journal: Malays J Pathol; 1994 Dec; 16(2):137-44. PubMed ID: 9053562.
    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.
