We encountered a 36-year-old white male patient with poorly differentiated lymphocytic lymphoma, whose lymph node cells showed a clonal cytogenetic change involving chromosome #14, i.e., 47,XY, + 2,der(14),t(14;14)(14pter----14q32;14q24----14q32++ +). In addition to this change, cells with a translocation between chromosomes #2 and another #14 [t(2;14)(q21;q24)], as well as a missing chromosome #8 were found. We have reviewed the literature dealing with two or more changes affecting chromosome #14 and discussed the importance of the cytogenetic change at band 14q32 in malignant lymphoma.
