... ients with lymphoma diagnosed by histopathologically were selected initially, among them 53 were confirmed by immunohistochemistry taken as study population finally. Results: Mean age was 39.2 ± 15.5 years, median age was 36 years within the range of 14 – 75 years. Males were predominant. Male female ratio was 4.3:1. Most of the samples were collected from cervical lymph node (84.1%). Most of the patients came with fatigue and significant weight loss. Maximum 42 (79.24%) cases were Non-Hodgkin's lymphoma and 11 (20.75%) cases were Hodgkin's lymphoma. Out of 42 non-Hodgkin's lymphoma, 27 (64.3%) were B-cell lymphoma and 15 (35.7%) were T-cell lymphoma. Among B-cell lymphoma, 19 (45.2%) were diffuse large B cell lymphoma, three (7.1%) were follicular lymphoma, three (7.1%) were mantle cell lymphoma, one (2.4%) was spleenic marginal zone lymphoma and one (2.4%) was Burkitt lymphoma. Among T-cell lymphoma, nine (21.4%) were peripheral T-cell lymphoma and six (14.3%) were adult T lymphoblastic lymphoma. Out of 11 Hodgkin's lymphoma, 10 (90.9%) were classical Hodgkin's lymphoma and one (9.1%) nodular lymphocyte predominant. Among classical Hodgkin's lymphoma, five (45.5%) were mixed cellularity, three (27.3%) were lymphocyte predominant and two (18.2%) were Nodular sclerosis. Out of 42 non-Hodgkin's lymphoma, 13 (30.95%) were indolent, 21 (50.00%) were aggressive and eight (19.05%) were very aggressive. Conclusion: In our study, it was found that 79.3% were non-Hodgkin lymphoma of which 64.3% were B-cell lymphoma & 35.7% were T-cell lymphoma and 20.7% cases were Hodgkin lymphoma of which 90.9% were classical Hodgkin's lymphoma, 9.1% nodular lymphocyte predominant Hodgkin's lymphoma.
