A 60-year-old patient undergoes a lymph node biopsy for generalized lymphadenopathy. Histopathology shows a nodular growth pattern composed of small cleaved and non-cleaved lymphocytes. Immunohistochemistry reveals CD20+, CD10+, BCL2+, and BCL6+. Cytogenetic analysis is most likely to reveal which of the following translocations?

Explanation

The description of a nodular growth pattern, small cleaved and non-cleaved lymphocytes, and the immunophenotype (CD20+, CD10+, BCL2+, BCL6+) are classic features of Follicular Lymphoma. Follicular Lymphoma is characterized by the t(14;18) translocation, which juxtaposes the BCL2 gene on chromosome 18 with the immunoglobulin heavy chain gene on chromosome 14, leading to overexpression of the anti-apoptotic BCL2 protein. - t(8;14) is associated with Burkitt Lymphoma. - t(11;14) is associated with Mantle Cell Lymphoma. - t(9;22) is the Philadelphia chromosome, associated with Chronic Myeloid Leukemia.
