However, unusual cases of bcl-1+ and CD5-MCL have been observed, posing a … Immunohistochemical staining is typically positive for CD5, CD19, CD20, and CD79b. CD5 is especially helpful in differentiating between MCL and low-grade lymphomas such as follicular lymphoma or marginal zone lymphoma, although, multiple CD5-negative cases of MCL [ 3 – 5 ] have been reported in the past few decades. MCL is typically CD5 positive, CD10 negative and CD23 negative. The T-cell marker CD43 may also be positive.

2 Approved by internal Molecular Testing Evaluation Committee (MTEC) for Mantle Cell Lymphoma but currently not available for on-site testing 2019-05-28 · Mantle cell lymphoma (MCL), which represents approximately 6% of non-Hodgkin's lymphoma (NHL) cases, remains the most challenging lymphoma to treat. As a result, this is one of the most active areas of investigation in lymphoma, in terms of translational research as well as in the development of novel approaches, some of which will be highlighted in this review. We report a case of a patient with two B‐cell lymphoproliferative disorders: CD5 − /CD23 + B‐cell chronic lymphocytic leukemia and CD5 + /CD23 − mantle cell lymphoma. These disorders were diagnosed simultaneously based on flow cytometry, immunohistochemistry, fluorescence in situ hybridization, and polymerase chain reaction–based molecular studies. Mantle cell lymphoma is a mature B-cell neoplasm usually composed of monomorphic small to medium-sized lymphoid cells with irregular nuclear contours. Leukemic non-nodal mantle cell lymphoma is defined as mantle cell lymphoma in which the patient presents with peripheral blood , bone marrow , and sometimes splenic involvement but without significant adenopathy .

Mantle cell lymphoma (MCL) is a distinct clinicopatho-logic entity recognized in the Revised European-American classification of lymphoid neoplasms1 and the current World Mantle cell lymphoma is usually, but not always, negative for BCL6, CD10 (see below), and CD23. Almost all MCLs, including rare CD5 − ones, are positive for cyclin D1, also known as BCL1, CCND1, or PRAD1.

Mantle cell lymphoma (MCL) typically expresses B-cell antigens and CD5 and overexpresses bcl-1 protein. However, unusual cases of bcl-1+ and CD5-MCL have been observed, posing a practical challenge for correct diagnosis and management. We identified 25 cases (48 samples) of bcl-1+ and CD5- lymphoma.

MCL is characterized by the translocation t(11;14)(q13;32) which results in the overexpression of cyclin-D1 and ultimately an uninhibited G1/S cell cycle transition. Introduction: Mantle cell lymphoma (MCL) is a B-cell neoplasm that has a characteristic immunophenotype of being positive for CD5, B-cell antigens and cyclin D1. A small subset of cases of MCL can be negative for CD5, approximately 5% in the literature. 2002-01-08 Mantle cell lymphoma (MCL) is an aggressive non-Hodgkin B-cell lymphoma typically expressing CD19, CD20, CD5, FMC-7, CyclinD1, and SOX-11 and harboring the IgH/CCND1 translocation.
