Clonal chromosome aberrations in a case of cutaneous T-cell lymphoma.

Cytogenetic analysis was performed on peripheral blood and on a skin infiltration from a patient with cutaneous T-cell lymphoma. The blood cells revealed no chromosome abnormalities; whereas, besides normal cells, the skin lesion yielded on aberrant clone with the following abnormalities: trisomies 8 and 17, a deletion of the short arm of chromosome 11, and formation of one marker chromosome with possible involvement of chromosome #14.
