Differential Diagnosis of Cyclin D1+ haem malignancies: Hairy Cell Leukaemia. Myeloma. Diffuse Large B Cell Lymphoma . INVESTIGATIONS . Laboratory CD5 positivity in B-cell lymphoproliferative disorders (LPD) is usually considered characteristic of either chronic lymphocytic leukemia (CLL) or mantle cell lymphoma (MCL).

MCL is typically CD5 positive, CD10 negative and CD23 negative. The T-cell marker CD43 may also be positive.

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. 8, 9 Cyclin D1 is a member of the cyclin D protein family. 10 B …

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.

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. 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. Mantle cell lymphoma (MCL) is a mature B-cell neoplasm that accounts for 3–10% of non-Hodgkin lymphomas, affecting predominantly middle-aged to elderly males [ 1 ].

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.
