Description
Background: LT is the standard of care for many pediatric liver disorders. Although long-term outcomes have improved, some rare complications such as transmission of occult donor tumors have been reported. Case report: An adolescent diagnosed with tyrosinemia was submitted to LT from a previous healthy donor due to HCC. Almost 8 months after LT, the patient presented a nodular hepatic lesion. Clinically, he had mild weight loss, lower limb edema, and gynecomastia. Thorax CT found lesions in the left lung parenchyma, which showed no increased uptake in PET SCAN. Liver biopsy revealed a carcinoma with desmoplastic stroma. ISS was withdrawn, and palliative chemotherapy was started for presumptive HCC relapse. AFP remained normal, but HCG had reached unexpected values of 1984 IU/L. As we requested detailed information about the other organ recipients from the same donor, we found that one of them passed away due to disseminated tumor. Five months after the beginning of chemotherapy, the patient underwent resection of liver segments V and VI. Histological examination confirmed liver metastatic choriocarcinoma. At the time of writing, with 11 years of follow-up, the patient had sustained remission with no signs of relapse. Discussion: This case reports a diagnostic challenge in an adolescent with a particular unique background and a very rare pattern of tumor transmission. The authors aim to highlight the risk of cancer-bearing organs reveled post-LT and to testimony the experience of the successful outcome after a choriocarcinoma transmitted by liver graft.
