	The primary site of lymphoma, either the lymph node or extra nodal site, is important in assessing clinical features, treatment options and outcome of the disease. Clinical presentation of DLBCL can be variable, usually depends on the site of disease involvement, rapid growth rate, enlarged lymph nodes, extra nodal mass infiltrating into tissues or obstructing organs. The enlarged lymphomatous mass may also exert severe pain. Patients usually experience fever, drenching night sweats, weight loss, anorexia, pedal edema (due to extensive pelvic lymphadenopathy), fatigue, chest discomfort or shortness of breath due to mediastinal lymphadenopathy.

	Due to the clinicopathologic, biological and genetic diversity, DLBCL is sub divided into morphological variants and molecular subtypes. Initial workup and evaluation of DLBCL has become increasingly complex partly due to the genetic abnormalities that are targets for specific therapy and play an important role in monitoring residual disease. Genomic studies help in clinical management, risk stratification, enrolling patients onto treatment protocols, clinical trials, and detection of therapeutic targets. GS, If IHC is positive for GCB like DLBCL, FISH and Cytogenetics for MYC, BCL2 or BCL6 gene rearrangement are recommended to rule out double and triple hit lymphoma.
