Late-Onset Peripheral T-Cell Lymphoma Not Otherwise Specified in a Liver Transplant Recipient: A Rare Subtype of Posttransplant Lymphoproliferative Disorder.

INTRODUCTION: Posttransplant lymphoproliferative disorder (PTLD) is a rare complication seen in the period after liver transplant. The commonest subtype is B-cell PTLD which is usually associated with Epstein-Barr virus (EBV) infection. T-cell PTLD is rare and the association with EBV is again rarer. CASE: Our patient, a 21-year-old young adult, presented to us with generalized lymphadenopathy, 5 years after liver transplantation. The biopsy of the lymph node was suggestive of peripheral T-cell lymphoma not otherwise specified, which was associated with EBV infection. The Positron emission tomography and computerised tomography (PET-CT) scan showed stage 3 disease. He was treated with standard cyclophosphamide, doxorubicin, etoposide, vincristine, and prednisolone chemotherapy and is currently in remission.
CONCLUSION: Peripheral T-cell lymphoma not otherwise specified is a rare subtype of PTLD and its association with EBV is even more rare. A few patients can achieve complete remission with standard chemotherapy.
