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 … We encountered two cases of CD5 − blastoid variant mantle cell lymphoma (MCL), prompting us to investigate the proportion of CD5 negativity in MCL and assess the diagnosis of aggressive MCL variants. Among 117 patients diagnosed with MCL, CD5 negativity was observed in 13% (13/104) of cases with classical MCL and 15% (2/13) of cases with MCL is typically CD5 positive, CD10 negative and CD23 negative. The T-cell marker CD43 may also be positive. 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.

chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), mantle cell lymphoma, and a subset (~10%) of diffuse large B-cell lymphoma. CD5 aberrant expression is useful in making a diagnosis of mature T-cell neoplasms. 2018-04-24 · Mantle cell lymphoma is considered an aggressive form of cancer that’s difficult to treat. By the time the cancer is diagnosed, it’s often spread to other areas of the body.

However, other neoplastic B-LPDs may express CD5, albeit infrequently. Mantle cell lymphoma (MCL), like CLL/SLL, is characterized by coexpression of CD5 and CD43 on the neoplastic B cells, along with CD19, CD20, and restricted light chains. However, in contrast to CLL/SLL, MCL typically shows moderate- to high-level expression of surface light chains CD20, CD22, and CD79b, with coexpression of FMC7 and little or no CD23 or CD200. Se hela listan på academic.oup.com The recent World Health Organization (WHO) classification defines mantle cell lymphoma (MCL) as a distinct entity characterized by a unique immunophenotype and a molecular hallmark of chromosomal translocation t(11;14)(q13;q32). We report an unusual case of an advanced stage of CD5 negative MCL with a blastoid variant with a massive bone marrow (BM) necrosis as an initial presenting feature Mantle cell lymphoma (MCL) characteristically express CD20, CD5, and cyclin-D1, carries the translocation t(11;14) (q13;q32) and typically has no expression of germinal center cell markers.

Mantle cell lymphoma (MCL) is a mature CD5+ B-cell lymphoma. Conventional MCL demonstrates low-grade morphology and aggressive clinical course.
