Fine needle aspiration cytology in the diagnosis of bone lesions.

摘要: Objective:  Fine needle aspiration cytology (FNAC) in combination with radiological examination has recently gained clinical recognition for evaluating skeletal lesions. We evaluated our experience the use of FNA diagnosing bone lesions emphasis on areas difficulty and limitations. Materials Methods:  Over a period 5 years was performed 66 cases Aspirations were done by cytopathologists using 22-gauge needle. Out unsatisfactory aspirate obtained 12 cases. Cytohistological correlation available 19 cases. Results:  Adequate aspirates categorized into neoplastic (27 cases) non-neoplastic Of 27neoplastic aspirates, 20 malignant (12 primary, 8 metastatic deposits) 7 benign. In group osteosarcoma correctly diagnosed 3 while other labeled as sarcoma NOS because lack osteoid. Metastatic deposits sub-typed 6 cases; from renal cell carcinoma (3 cases), proststic adenocarcinoma, follicular thyroid, squamous carcinoma. Neoplastic comprised cysts 21 chronic osteomyelitis. Thirteen tuberculous osteomyelitis. Conclusions:  is frequent indication metastases where distinct cytologic features can even identify an unknown primary. However, diagnosis primary tumours limited precise subtyping tumours. emerged cost effective tool initial both bone.
