Long-term survival after choriocarcinoma transmitted by liver graft: A successful report in pediatric transplantation.

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.

Left atrial extension of a Wilms' tumor.

Isolated involvement of the left heart chambers by metastases of malignant tumors is extremely rare. We report a case of an 8-year-old child, with a left atrial metastasis of a Wilms' tumor detected in a control nuclear magnetic resonance 1 year after left inferior lobectomy for metastatic extension of the kidney tumor, which was diagnosed 4 years earlier. The metastasis was excised en bloc with a disc of the posterior left atrial wall.

Neonatal Paratesticular Neuroblastoma Misdiagnosed as In Utero Torsion of Testis.

Reports of neuroectodermal primary scrotal tumors are scarce. Primary paratesticular neuroblastomas seem even rarer, and only five infants with this condition have been previously described. To the authors' knowledge, this would be the first report of a neonatal congenital paratesticular neuroblastoma.
