Introduction:
Although spontaneous tumor rupture is a serious complication of hepatoblastoma, there is no consensus regarding the treatment strategy in infants. We report a patient with lung metastases who had a ruptured hepatoblastoma prior to the start of the scheduled chemotherapy and was successfully treated with a combined treatment including liver resection, lung resection, and chemotherapy.
Presentation of case:
A 22-month-old boy with a ruptured hepatoblastoma and lung metastases underwent an emergency laparotomy with complete tumor resection, followed by chemotherapy. Moreover, a barely detectable metastatic lung lesion shown by a chest CT scan was resected after the fifth chemotherapy treatment. Both postoperative and chemotherapy courses were uneventful. The patient survived without any recurrent hepatoblastoma 2 years after the emergency surgery despite the poor prognosis indicated by distant metastases at the time of diagnosis.
Discussion:
Because rupture itself can be the main cause of death in patients with hepatoblastoma, emergency tumor hemostasis is essential. However, there are no reports comparing the prognosis of the treatment method performing tumor hemostasis alone, tumor resection after chemotherapy, and tumor hemostasis and resection at the same time. The clinical course of the patient indicates that performing tumor hemostasis and resection simultaneously and lung resection after chemotherapy is an effective option to treat a ruptured hepatoblastoma with disseminated tumors and lung metastases if the patient's condition is stable.
Conclusion:
Aggressive treatment with surgery and chemotherapy is an effective option for ruptured hepatoblastoma with disseminated tumors and lung metastases in infants.
