Lymphomas, Mantle-Cell

Medical Condition:
Lymphomas, Mantle-Cell

A rare form of non-Hodgkin lymphoma having a usually diffuse pattern with both small and medium lymphocytes and small cleaved cells. It accounts for about 5% of adult non-Hodgkin lymphomas in the United States and Europe. The majority of mantle-cell lymphomas are associated with a t(11;14) translocation resulting in overexpression of the cyclin D1 gene (GENES, BCL-1).
