Abstract

Posttransplantation allograft malignancy of donor origin is a rare complication after liver transplantation. In the case described, subjective fevers and nonspecific abdominal complaints nearly 6 months following cadaveric liver transplantation in a young woman prompted an evaluation which was remarkable for a large central liver mass. A poorly differentiated squamous cell carcinoma was diagnosed, but was unresectable at exploration. The tumor was confined to the liver. Histocompatibility testing using polymerase chain reaction (PCR) amplification techniques identified both donor and recipient HLA alleles. The patient was treated with chemoembolization, systemic chemotherapy and cessation of immunosuppression. Repeat biopsy 2 months later showed the tumor to be completely necrotic. With decompensated liver disease, she was relisted and retransplanted. More than 2 years later she remains disease-free with complete pathological remission. This is the only reported case of squamous cell carcinoma of donor origin arising in a transplanted liver.
