Immunoarchitectural patterns in nodal marginal zone B-cell lymphoma: a study of 51 cases.
Nodal marginal zone lymphoma (NMZL) represents a rare and heterogeneous group that lacks markers specific for the diagnosis. We evaluated morphologic and immunoarchitectural features of 51 NMZLs, and the following immunostains were performed: CD20, CD21, CD23, CD5, CD3, CD43, CD10, Ki-67, BCL1, BCL2, BCL6, HGAL, and LMO2. Four immunoarchitectural patterns were evident: diffuse (38 [75%]), well-...
متن کاملMarginal Zone B-cell lymphoma
Extra-nodal MZBCL of MALT type (7% of all NHL) is an indolent disease involving most often the stomach, where it usually follows chronic gastritis due to Helicobacter pylori (HP) infection. The disease may also localize in the lung, the thyroid, the salivary gland, the orbit. Splenic MZBCL (1% of all NHL on histologic samples) usually, though not invariably, presents splenomegaly associated cir...
متن کاملPrimary cutaneous marginal zone B-cell lymphoma.
Primary cutaneous marginal zone B-cell lymphoma (PCMZL) is included as one of the major types of primary cutaneous B-cell lymphoma in the revised World Health Organization-European Organization for Research and Treatment of Cancer classification. Clinically, PCMZL is an indolent disease and has an excellent prognosis. PCMZL is composed of a polymorphous infiltrate that includes centrocyte-like,...
متن کاملNodal marginal zone B-cell lymphomas may arise from different subsets of marginal zone B lymphocytes.
Nodal marginal zone B-cell lymphoma (MZL) is a rare and not extensively studied entity that accounts for approximately 2% of all non-Hodgkin lymphomas. Complementarity-determining regions 2 and 3 (CDR2, CDR3) of the immunoglobulin heavy-chain variable region (V(H)) genes were amplified by polymerase chain reaction (PCR), cloned, and sequenced in 8 patients with nodal MZL. All showed a potential...
متن کاملExtranodal pulmonary marginal zone B-cell lymphoma☆
AIM Extranodal mucosa-associated lymphoid tissue (MALT) arises a number of epithelial tissues, including the stomach, salivary gland, lung, small bowel, and elsewhere. Here we present a male patient with an uncommon site of extranodal MALT such as a pelvic mass diagnosed after a long period of evaluation, which initially presented with an incidental pulmonary nodule. METHOD We report a 60 yea...
