Ewing's sarcoma of bone--a study of 71 cases by fine needle aspiration cytology.
Fine needle aspiration cytology (FNAC) plays immense diagnostic role in Ewing's sarcoma of bone. As clinically and sometimes radiologically Ewing's sarcoma mimics osteomyelitis of bone, FNAC is of great help to distinguish these 2 lesions and can avoid unnecessary incisional biopsies in most of the cases. At present limb salvage therapy is replaced by chemotherapy and radiotherapy. Moreover most of the patients present with gross soft tissue involvement where exact categorisation of malignant bone tumour is not possible by radiological means. FNAC is of great benefit to the clinicians and the patients as it provides a quick and accurate report and surgical interventions can be avoided in most of the cases. This paper highlights the cytological appearance of Ewing's sarcoma of bone in 71 cases. A conclusive diagnosis can be made with the help of special stains and cell block study. The diagnostic accuracy was 100% without any complication.
