Post-transplant lymphoproliferative disorder presenting on post-transplant Day 35 as a pulmonary parenchymal infiltrate—a case report

摘要

Post-transplant lymphoproliferative disorder (PTLD), a rare but serious complication of solid organ transplantation, is classified into early-onset and late-onset subtypes. Early-onset PTLD occurs a median of 4–11 months after lung transplantation. It rarely presents in the first 2 months post-transplant. Early-onset PTLD usually presents as a solitary pulmonary nodule. We present a unique case of early-onset PTLD that was diagnosed on post-operative Day 35 and presented as a pulmonary parenchymal infiltrate. This case is also exceptional in that the patient had a significant clinical response to only a single dose of rituximab.
