RESUMEN
Posttransplant lymphoproliferative disorder (PTLD)is recognized as a significant and morbid complication of organ transplantation. The majority of PTLD is of B cell origin and strongly associated with Epstein Barr virus (EBV). T cell origin is uncommon and has a poor prognosis. There are only a few cases of PTLD of T cell origin, associated with EBV. We have experienced a case of angiocentric T cell lymphoma in nasal cavity, associated with EBV in a renal transplanted recipient. The patient was 25 years old woman who received transplant from her brother in 1995. Angiocentric T cell lymphoma was developed 33 months after the transplantation. We detected EBV mRNA in the neoplastic cells by in situ hybridization. She was treated by radiotherapy and is in complete remission state at present.
