Background: Regional lymph nodes play an important role in acting as anatomic barriers to systemic dissemination of tumor cells. This reflects in the host immunologic response. Oral squamous cell carcinoma, is known to be associated with early deficiencies of cell-mediated immunity, the pathology of which is reflected in the histology of the regional lymph nodes. Aim : The goal of this study was to study the different immunity reactions in the lymph nodes and to correlate it with the histopathology of tumor proper. Materials and Methods: Out of 40 head and neck dissections, 30 were male and 10 females within the age range of 21-72 years. According to Tumor Node Metastasis classification, there were 12 cases of stage II and stage III, respectively while 16 were of stage IV. A total of 372 nodes were histologically evaluated. The harvested lymph nodes were categorized into metastatic and non-metastatic nodes exhibiting four patterns as: Lymphocyte predominance pattern, germinal center predominance pattern, lymphocyte depleted pattern and unstimulated pattern. Results: The predominant pattern of lymph node reactivity was of lymphocyte predominance (199 nodes) followed by germinal center predominance (117 nodes); lymphocyte depleted (17 nodes) and unstimulated node pattern (39 nodes). Twenty-seven nodes were positive for metastasis. A statistically significant relationship (P = 0.0019 and P = 0.0290, chi square, respectively) was observed between the number of nodes harvested and stage and level of lymph nodes. A brief follow-up period of 3 years was carried out. Conclusion: Further studies relating the immuno-morphologic assessment of the lymph nodes in conjunction with other factors may be helpful in assessing the metastases risk of the individual.
