We report a case of a 45-year-old female who developed an ALK-positive anaplastic large cell lymphoma (ALCL) 9 years after renal transplant. The patient underwent a cadaveric renal transplant for diabetic nephropathy, and presented 9 years later with fever and multiorgan dysfunction. The initial CT scans showed multiple enlarged supra- and infradiaphrgamatic lymph nodes. A CT-guided core needle biopsy of a retroperitoneal lymph node revealed ALK positive ALCL. She received six cycles of cyclophosphamide, adriamycin, vincristine, etoposide, and prednisone, and has been in remission for over 3 years. Monomorphic T-cell posttransplant lymphoproliferative disorder (PTLD) is an established but rare entity of PTLD and generally carries poor prognosis. This is a case report of a late PTLD with pathology reporting an aggressive T-cell lymphoma that has been successfully treated with multiagent chemotherapy.
