Biphenotypic bigenotypic lymphoma with simultaneous expression of PAX5/BSAP and B- and T-cell markers
Research output: Contribution to journal › Article
Lymphomas are currently categorized according to their origin from a B or T lymphocyte. Immature and less commonly mature (peripheral) lymphomas may harbor rearrangements of both the B- and T-cell antigen receptor genes (dual genotype or bigenotype). Rarely, cells in lymphoma with a single genotype simultaneously express both B- and T-cell markers (biphenotypic lymphomas). We discuss the diagnostic and clinical implications in the case of a 42-yr-old female with a peripheral CD30(+) lymphoma that displayed both characteristic B- and T-cell surface antigens and clonal rearrangement of B- and T-cell antigen receptor gene loci. Simultaneous nuclear expression of the transcription factor gene PAX5 suggested that this major driver of B-cell differentiation did not preclude expression of CD3 epsilon, generally assumed to be a T-cell associated antigen.
