Breakpoints of 11q25 in Three Similar Cases of B Non Hodgkin's Lymphoma

We report three cases of small B cell non Hodgkins lymphoma, two with plasmacytoid differentiation, presenting with a similar clinical picture and identical immunophenotype, who cytogenetically had breakpoints involving band 11q25. We suggest that this breakpoint may define a group of lymphomas closely related to the diffuse small cleaved cell lymphomas with t(11;14)(q13;q32).
