Background: The aim of the study was to evaluate the role of apoptotic index (AI) in premalignant and malignant squamous lesions of different sites on light microscopy. Materials and Methods: Retrospective study of 75 cases of premalignant and malignant squamous epithelial lesions of different sites was done. All slides were H and E stained, screened for apoptosis under ×40. AI was calculated as the number of apoptotic cells and apoptotic bodies, expressed as percentage of total number of tumor cells counted in each case. Results: On statistical analysis, it was found that the difference in the apoptotic indices in all the subgroups of dysplasia was not statistically significant. However, the significant statistical difference was found within the malignant group, P value between well-differentiated squamous cell carcinoma (SCC) and moderately differentiated SCC (MDSCC) was <0.0001. P value obtained between MDSCC and poorly differentiated SCC was 0.0006. Conclusion: We conclude that apoptotic indices are useful in distinguishing between benign and malignant squamous lesions. Several indices such as proliferating index (Ki-67) and AgNOR count are not routinely available in various hospitals, especially in developing countries. The advantage of this technique is that it can be calculated in routine H and E stained sections, and so it saves time. Although it is labor-intensive, it is cost-effective method which can benefit the patient as it correlates well with tumor aggressiveness and thereby increasing the prognosis of the patients.
