Isolated hepatoblastoma arising from the hepatogastric ligament: a case report.

BACKGROUND

Almost all hepatoblastomas are isolated to the liver. Hepatoblastoma arising from and limited to extrahepatic tissue is an extremely rare clinical entity.

CASE PRESENTATION: Here we present a case of a 7-year-old Chinese boy of Han ethnicity with hepatoblastoma originating from the hepatogastric ligament. A complete resection was performed and the entire course was uneventful. He received six cycles of postoperative chemotherapy and had no signs of recurrence for 3 years after surgery.

CONCLUSIONS

Hepatoblastoma arising from extrahepatic tissue is extremely rare. A pedunculated hepatoblastoma is prone to hemorrhage and tumor metastasis. The best treatment for a long-term cure is complete resection of the primary tumor combined with chemotherapy.
