Background: The classification of benign versus malignant pleural effusions frequently leads to a diagnostic conundrum. Evaluation of morphology and clinical findings are frequently necessary for categorization. Cell blocks enhance the chance of a diagnosis when done in addition to standard cytology smears. This will support the medical professionals in managing the patient and assessing the course of the illness. This study compared the cytology of smears with sections of cell blocks from pleural effusions. Methods: For one year, the Department of Pathology at Nalanda Medical College in Patna, Bihar, conducted this hospital-based cross-sectional analytical study. Results: Each technique was evaluated based on four criteria: the quantity of baseline blood, the production of diagnostic cell material, the degree of cellular degeneration, the presence of cellular trauma, and the preservation of architectural elements. When comparing cell block sections to smears cytology, there was more diagnostic material present and appropriate architecture preservation; however, background blood, cellular trauma, and degeneration were less well-appreciated in the cell block sections that scored higher. Conclusion: Cell block technique processing should be done on a regular basis, particularly in cases that are cytologically, radiologically, and clinically suspected to be malignant.
