Introduction: Fine-needle aspiration cytology (FNAC) has certain disadvantages despite being the most commonly used procedure in the initial diagnosis of any swelling. In such cases, a cell block (CB) study can be a valuable adjunct to smears for establishing a more definitive cytopathological diagnosis. Therefore, this study was conducted to evaluate the efficacy of CB with FNAC and to compare the findings of the CB and FNAC with histopathology as the gold standard. Materials and Methods: The study was conducted in the department of pathology at our institute. All the cystic/solid lesions sent for fine-needle aspiration, which yielded sufficient material for the CB, were studied along with detailed clinical history. Results: Out of 66 cases of FNAC and CB, 35 cases were sent for histopathology. The mean age of the patients was 41.36 years, and female patients were more in number (73%). Benign lesions (71.4%) were more than malignant ones (29.6%). The CB section had more thyroid lesions (31%). The diagnostic accuracy of FNAC was found to be 94.28%, while that of CB was 97.14%. Conclusion: Although FNAC is the first line of investigation for mass lesions, and still, to make the best possible use of an aspirate, smears should be used together with CB preparation to provide the best possible morphological and histological diagnosis.
