Pathological spectrum of lung lesions diagnosed by sputum cytology: A three years retrospective study in a tertiary health care centre of North India

Sputum Cytology is a cheap and noninvasive investigation contributing significantly to the workload of Cytopathology Laboratories. However, over years, use has depreciated. It been taken by more advanced procedures like Broncho Alveolar Lavage Trans Bronchial Needle Aspiration, which are comparatively invasive expensive requiring much higher learning curve. Hence, usefulness samples needs be explored in resource limited settings. To study spectrum Lung lesions diagnosed using with Histopathological correlation wherever possible. : This was three years retrospective study. Data patients who had come sputum sample retrieved from archives cytopathology lab between July 2019 June 2022. findings were correlated histopathological diagnosis, Out total size 143, 67 showed inflammatory infiltrate, 1 out confirmed malignant on biopsy. 17 cases suspected malignant, 15 Other revealed presence fungal infection, dysplasia no frank malignancy reactive changes. Our shows that testing can quite an accurate method early diagnosis many lung including malignancies. The Sensitivity Specificity for 83.33% 95% respectively. Therefore, it applied as cheaper, ideal screening test detection pathologies especially poor
