Trisomy 5 and t(5;14)(q11;q32) as the sole abnormalities in two different clones from a centroblastic non-Hodgkin's lymphoma
A 62-year-old previously healthy woman presented with a centroblastic non-Hodgkin's lymphoma in the thyroid. Chromosome analysis revealed two unrelated clones, 47,XX,+5 and 46,XX,-14,+der(14)t(5;14)(q11;q32). The two clones may reflect a polyclonal origin, or they may be the descendants of the same neoplastically rearranged cell. In the latter case, the clonal aberrations are either secondary to a
