Extracutaneous B‐cell post‐transplantation lymphoproliferative disorder and cutaneous T‐cell post‐transplantation lymphoproliferative disorder in a child.

A 12-year-old girl who had a history of liver transplantation due to congenital biliary atresia, presented with a 6-month history of an enlarging erythematous plaque with crust on her right buttock. A diagnosis of EBV-positive cutaneous PTLD of T-cell lineage was made. This case suggests that B-cell and T-cell PTLD, both associated with EBV infection, can co-occur in a liver transplant recipient. [Extracted from the article]
