We present a 9-month-old male with mosaic trisomy 18 with a right hepatic lobe mass. The tumor was completely resected and identified as pure fetal histology hepatoblastoma but contained increased mitotic activity. Adjuvant chemotherapy consisted of cisplatin, vincristine, and 5-fluorouracil. After the first and fourth cycles of chemotherapy, recurrent tumor developed. The patient underwent rescue orthotopic liver transplantation, and is currently alive without evidence of hepatoblastoma 28 months after transplantation. This report demonstrates the use of orthotopic liver transplantation in a child with mosaic trisomy 18 and hepatoblastoma.

ABSTRACT: We report a case of hepatoblastoma in a 10-year-old girl with mosaic-type trisomy 18. A comprehensive literature review reveals only 2 cases involving mosaic trisomy 18 patients. Our patient underwent an abbreviated chemotherapy course before complete surgical resection. Her hepatoblastoma did not contain cells with trisomy 18. The conservative management approach resulted in a successful outcome; she remains disease free >2 years after surgery. Along with presenting a literature review, this report demonstrates a favorable outcome in a mosaic trisomy 18 child with hepatoblastoma where tumor cells lacked a trisomy 18 karyotype.Journal of Pediatric Hematology/Oncology 03/2012; 34(4):e145-8.

ABSTRACT: Trisomy 13 (T13) is a rare autosomal aneuploidy. Greater than 90% of patients die during the first year of life. Malignancies reported in association with T13 include two cases of Wilms tumor and one case of pilocytic astrocytoma. There is no previous report of hepatoblastoma in patients with T13. We report a unique case of hepatoblastoma in a 15-month-old female with constitutional T13. Our patient was born at 38 weeks gestation and was noted to have phenotypic features consistent with T13. Genetic testing confirmed an abnormal karyotype of 47,XX,+13 in all cells. At fifteen months of age she was noted to have a right hepatic lobe mass on a routine follow-up renal ultrasound for hydronephrosis. Serum alpha-fetoprotein level was 55,300 ng/ml. Staging work-up revealed the absence of metastases. She underwent a complete surgical resection with right hepatic lobectomy. Histopathology was consistent with hepatoblastoma, mixed epithelial and mesenchymal type. She had a protracted postoperative course complicated by Enterobacter aerogenes urosepsis, a significant biloma, chronic pancreatitis, and apneic episodes of uncertain etiology. She received four courses of doxorubicin monotherapy without any severe or unexpected toxicity. She continues to be in remission 8 months following diagnosis. This is the first reported case of hepatoblastoma in a child with constitutional T13. This may represent a non-random association, as somatic trisomy of chromosome 13 in hepatoblastoma tumors has been previously described in the literature. Prolonged survival may have allowed for hepatoblastoma to present in our patient. © 2013 Wiley Periodicals, Inc.American Journal of Medical Genetics Part A 02/2014; 164(2).
