Translocation t(8;10)(q12;p14) in lymphoproliferative disorders

Cytogenetic studies were performed in two patients with a B-cell lymphoproliferative disease in progressive phase characterized by leukocytosis and important splenomegaly. In both patients an identical chromosome marker derived from a t(8;10)(q12;p14) translocation was found. This chromosome anomaly was associated with other abnormalities characteristic for lymphoid malignancies, i.e. a structural rearrangement of the long arm of chromosome 11 and a 14q+ in both patients. This new t(8;10) translocation may be a marker of accelerated phase in lymphoid disorders.
