You may hear your doctor call your condition a type of "non-Hodgkin's CD5 NEGATIVE MANTLE CELL LYMPHOMA. DISCUSSION: Mantle cell lymphoma (MCL) is an aggressive and untreatable B cell neoplasm, and comprises approximately 3-10% of non-Hodgkin lymphomas. It occurs in middle aged to older individuals with a median age of approximately 60 years with a marked male predominance. CD5 positivity in B-cell lymphoproliferative disorders (LPD) is usually considered characteristic of either chronic lymphocytic leukemia (CLL) or mantle cell lymphoma (MCL). However, other neoplastic B-LPDs may express CD5, albeit infrequently.

Mantle cell lymphoma is a mature, virgin B-cell neoplasm characterized immunologically by a panB+, CD5+, CD23−, cyclin D1+ phenotype and genetically by t(11;14)(q13;q32) with overexpression of MCL is a subtype of B-cell lymphoma, due to CD5 positive antigen-naive pregerminal center B-cell within the mantle zone that surrounds normal germinal center follicles. In addition, the cells do not die as they should and therefore accumulate in the lymphoid system, including lymph nodes and the spleen, with non-useful cells eventually Various T cell lymphomas: enteropathy associated, hepatosplenic alpha-beta and gamma-delta, large granular lymphocytic lymphoma; Most B cell lymphomas other than mantle cell or CLL (although there rarely are CD5+ variant forms), Reed-Sternberg cells in Hodgkin lymphoma 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. CD5 expression was assessed by flow cytometric Mantle cell lymphoma (MCL) represents 4% to 9% of all non-Hodgkin lymphomas and is characterized by CD5 and cyclin D1 expression and t (11;14) (q13;q32). However, about 5% of MCL lack CD5 expression and is poorly characterized.

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. The classic prototypes of CD5 + /CD10 − B-cell lymphomas are small lymphocytic lymphoma (SLL) and mantle cell lymphoma (MCL). Small lymphocytic lymphoma and chronic lymphocytic leukemia (CLL) are 2 different presentations of the same disease.

Abstract. Mantle cell lymphoma (MCL) represents 4% to 9% of all non-Hodgkin lymphomas and is characterized by CD5 and cyclin D1 expression and t (11;14) (q13;q32). However, about 5% of MCL lack CD5 expression and is poorly characterized. Here, we present 58 patients with CD5 negative (CD5) MCL and compared them with a group of 212 typical CD5 positive (CD5) MCL cases. Abstract 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. CD5 80%. Large cell transformation.

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. CD5 expression was assessed by flow cytometric analysis alone (1 case), immunohistochemical analysis alone (17 cases), or dual flow cytometric/immunohistochemical methods (7 cases). Abstract.

Background: The CD5 antigen is found on 95% of thymocytes and 72% of peripheral blood lymphocytes. In lymph nodes, the main reactivity is observed in T-cell areas.
