Abstractor Notes
Patients may present with nodal or extranodal disease. The most common extranodal site is the gastrointestinal site (stomach and ileocecal region). Other common sites of extranodal presentation include the bone, testes, spleen, Waldeyer ring, salivary glands, thyroid, liver, kidneys, and adrenal glands.
Patients usually present with a rapidly enlarging tumor mass at single or multiple nodal or extranodal sites. Many patients are asymptomatic, but B symptoms may be present. Specific localizing symptoms may be present and are highly dependent on the site of extranodal involvement.

Diagnostic Confirmation
This histology can be determined by positive histology (including peripheral blood) with or without genetics and/or immunophenotyping. Review the Definitive Diagnostic Methods, Immunophenotyping and Genetics Data sections below, and the instructions in the Hematopoietic Manual for further guidance on assigning Diagnostic confirmation.

Definition
Diffuse large B-cell lymphoma (DLBCL) is a neoplasm of medium or large B lymphoid cells whose nuclei are the same size as, or larger than, those of normal macrophages, or more than twice the size of those of normal lymphocytes, with a diffuse growth pattern.
Morphological, biological, and clinical studies have divided DLBCLs into morphological variants, molecular subtypes, and distinct disease entities.
Diffuse large B-cell lymphoma associated with chronic inflammation is a lymphoid neoplasm occurring in the setting of longstanding chronic inflammation and showing association with EBV. Most cases involve body cavities or narrow spaces. Pyothorax-associated lymphoma (PAL) is the protypical form, developing in the pleural cavity of patients with longstanding pyothorax.
EBV-positive diffuse large B-cell lymphoma (DLBCL), not otherwise specified (NOS), is an EBV-positive clonal B-cell lymphoid proliferation. Excluded from this category are cases of lymphomatoid granulomatosis, cases with evidence of acute or recent EBV infection, other well-defined lymphomas that may be EBV-positive (such as plasmablastic lymphoma and DLBCL associated with chronic inflammation), and EBV-positive mucocutaneous ulcer. This disease was formerly designated as EBV-positive DLBCL of the elderly. The elderly designation has been removed.
Fibrin-associated diffuse large B-cell lymphoma is an unusual form of diffuse large B-cell lymphoma associated with chronic inflammation. It is not mass forming and does not directly produce symptoms, but is discovered incidentally on histological examination of surgical pathology specific excised for various pathologies other than lymphomas.
High-grade B-cell lymphoma (HGBL) is a group of aggressive, mature B-cell lymphomas . There are two categories of HGBL.
1) HGBL with MYC and BCL2 and/or BCL6 rearrangements, encompasses all B-cell lymphomas that have a MYC (8q24) rearrangement in combination with a BCL2 (18q21) and or a BCL6 (3q27) rearrangement, i.e. the so-called double-hit and triple-hit lymphomas.
2) HGBL, NOS encompasses cases that either have features intermediate between DLBCL and BL, or appear blastoid, but by definition do not harbor a genetic double hit.
Primary cutaneous diffuse large B-cell lymphoma (PCLBCL), leg type, is a PCLBCL composed exclusively of centroblasts and immunoblasts, most commonly arising within the leg.
Primary diffuse large B-cell lymphoma (DLBCL) of the CNS is defined as DLBCL arising within the brain, spinal cord, leptomeninges or eye. Excluded are lymphomas of the dura, intravascular large B-cell lymphomas, lymphomas with evidence of systemic disease or secondary lymphomas, and all immunodeficiency-associated lymphomas.
