title: Hepatosplenic gammadelta-T-cell lymphoma with leukemic course after renal transplantation.
abstract: Hepatosplenic gammadelta-T-cell lymphoma (HSTCL) is a rare extranodal T-cell non-Hodgkin's lymphoma (T-NHL) with only 46 well-documented cases in medical literature. Notably, a relatively high number of these case reports (15%) describe the occurrence of HSTCL after solid organ transplantation. We describe the case of a 45-year-old man who developed a leukemic HSTCL 5 years after renal transplantation and continous immunosuppression with cyclosporine A and prednisolone. After a rapid clinical course, the patient died and autopsy was performed. The malignant lymphocytes showed a natural killer-like gammadelta-T-cell phenotype (CD2(+), CD3(+), CD7(+), TCR gammadelta(+), CD56(+), TIA-1(+), CD4(-), CD8(-), and TCR alphabeta(-)) and infiltrated the sinusoids of liver and the red pulp of the spleen. Cytogenetically, an isochromosome 7q, trisomy 8, Y-loss, and a translocation t(1;4) was detectable. This case shows the difficulties of recognizing HSTCL early in the clinical course and underlines that all types of T-NHL, nodal as well as extranodal, have to be considered in the differential diagnosis of posttransplantation lymphoproliferative disorders. Moreover, HSTCL seems to occur as a specific late complication of solid organ transplantation.
