PTLD is a rare complication after liver transplantation, but it may pose a threat to the life of a liver transplant recipient. Thus, in the absence of curative treatment, the overall prognosis for ALPS remains guarded, necessitating long-term clinical studies to better understand its natural history. PTLD incidence was 1.
