![]() ![]() STT are defined as mesenchymal proliferations that occur in the extraskeletal, nonepithelial tissues of the body, excluding the viscera, coverings of the brain, and lymphoreticular system, and benign tumors are more common than malignant counterparts (sarcomas) with a ratio of at least 100 : 1. The rarity of primary tumors of soft tissue and large range of different types of tumors, the diagnosis and classification of soft tissue tumors become most difficult areas in surgical pathology and absence of recognizable tissue architectural patterns in cytological preparation makes diagnosis by fine needle aspiration cytology (FNAC) even more difficult. The field of soft tissue tumors (STT) is enormously vast, and yet as cytologically, relatively undiscovered. FNAC is a very important preliminary diagnostic tool in palpable soft tissue lumps with high degree of correlation with the final histopathology report. value was 0.0001 which shows statistically extreme significant correlation. The sensitivity, specificity, positive predictive value, negative predictive value, and efficiency were 70%, 100%, 97.90%, 100%, and 98%, respectively. All diagnostic FNAC results were compared for diagnostic concordance using histology results as the “gold standard.” Results. The smears were studied for cytological diagnosis and were categorized as benign, suspicious of malignancy, and malignant along with specific subtyping of the lesion. FNAC air dried smears were stained with Giemsa stain and 95% ethanol fixed smears were stained with Papanicolaou stain. 150 cases of soft tissue tumors were included in this study for cytologic and histologic correlation. To assess the utility of FNAC in diagnosing soft tissue tumors and to determine their patterns compared with with the respective histopathology results. The absence of recognizable tissue architectural patterns in cytological preparation makes diagnosis by FNAC more difficult. Soft tissue tumors are defined as nonepithelial extraskeletal tissue of the body exclusive of the reticuloendothelial system, glia, and supporting tissue of various parenchymal organs. ![]()
