Background: Soft tissue tumours are very rare. They are diagnosed initially by Fine needle aspiration cytology (FNAC). The present study was conducted with the aim to study the acceptability and diagnostic accuracy of cytodiagnosis in soft tissue lesions, to evaluate the reliability of cytodianosis as compared conventional histological paraffin section and to assess nuclear grade in various soft tissue lesions.Methods: The present study was conducted on 140 patients of soft tissue tumours during the period from August 2002 to July 2003 in the Department of pathology and microbiology, LLRM medical college, Meerut. FNAC was done in 132 cases and histopathology was conducted in 86 cases and correlation of those results was done.Results: Diagnosis of STT by FNAC was done in 132 cases. In benign tumours maximum number of cases (28) was in the age group of 20-29 years and in malignant tumours maximum number of cases (7) was in the age group of 40-49 years. 110 (83.3%) cases were benign and 22 (16.7%) cases were found to be malignant. Maximum number of STT was observed in trunk followed by limb extremities. Male preponderance was observed in the study. The overall accuracy of the present study was 97.7%. Accuracy for diagnosing benign soft tissue tumours was 100% and for malignant STT was 94.5%. The sensitivity, specificity and predictive value of the present study was 100%, 98.6% and 93.3%.Conclusions: FNAC plays a very important role in initial diagnosis of soft tissue tumours. It provided acceptable diagnostic accuracy when supported by histopathology.
