Extrahepatic metastasis in patients with hepatocellular carcinoma (HCC) occurs frequently. The most common site of metastasis is the lung, followed by regional lymph nodes and bones. However, gastrointestinal metastasis of HCC is a rare condition and solitary polypoid metastatic lesion on stomach without any evidence of direct invasion from primary mass is very rare. These metastatic lesions are usually asymptomatic, and most are discovered at postmortem examination or are found incidentally during laparotomy. The choice of treatment for gastrointestinal metastatic lesion of HCC includes surgery, transarterial chemoembolization, and local injection but the treatment is often difficult and unsuccessful. We report a case of 69 years old man who presented disappearance of a polypoid metastatic lesion of HCC on the gastric fundus by transarterial chemoembolization.

A 63-year-old man with a history of hepatitis-B-related hepatocellular carcinoma (HCC) in the left lateral portion of the liver received repeated transcatheter arterial chemoembolization (TACE) and salvage radiotherapy. Two months after completing radiotherapy, he presented with dysphagia, epigastric pain, and a protruding abdominal mass. Computed tomography showed that the bulging mass was directly invading the adjacent stomach. Endoscopy revealed a fistula from the HCC invading the stomach. Although the size of the mass had decreased with the drainage through the fistula, and his symptoms had gradually improved, he died of cancer-related bleeding and hepatic failure. This represents a case in which an HCC invaded the stomach and caused a hepatogastric fistula after repeated TACE and salvage radiotherapy.

Bone is a common site of metastasis in patients with hepatocellular carcinoma (HCC). We report a rare case of rib metastasis from HCC treated by transcatheter arterial chemoembolization (TACE). A 55-year-old man with liver cirrhosis presented with right lower chest pain. The diagnosis was an HCC with a bone metastasis in the right eighth rib. Intra-arterial injections of doxorubicin mixed with Lipiodol and Gelfoam particles were instituted through the right eighth intercostal artery. Computed tomography and a Tc99-labeled scan performed 2 months after the third TACE revealed no viable HCC in the right eighth rib.

Undifferentiated sarcoma is an uncommon primary malignant tumor of the liver typically occurring in older children. It is also referred to as malignant mesenchymoma, fibromyxosarcoma, or mesenchymal sarcoma. We experienced a case of undifferentiated sarcoma in 72-year-old male. Contrast enhanced liver CT scan revealed a 3.4 cm heterogeneously enhancing, ill-defined, and low attenuated mass in the left liver and subtle intrahepatic duct dilatation. And, in tubogram, there were segmental stenosis and occlusion from the hilum to the proximal common bile duct. We did ultrasonography guided liver biopsy. The pathologic finding revealed infiltrative growth of atypical cells with rhabdoid features. Some atypical cells showed clear cytoplasm, but no organoid pattern was identified. The stroma around atypical cells was filled with eosinophilic hyaline material. These tumor cells were positive for vimentin only, and the tumor was consistent with undifferentiated sarcoma of the liver.

Spontaneous regression of hepatocellular carcinoma (HCC) is extremely rare. We report a case of 67-year-old man having HBV-associated HCC with multiple lung metastases which regressed spontaneously. The patient had single liver mass and received surgical resection. The mass was confirmed as HCC histopathologically. Nine years after surgical resection, a 3.3 cm sized recurred HCC was detected on the resection margin in CT scan. Transarterial chemoembolization (TACE) was performed 3 times, and lung metastases developed thereafter. The patient received 2 more sessions of TACE, however, metastatic lung nodules were in progress very rapidly. We decided to stop TACE and followed the patient regularly without any anti-cancer treatment. Nine months after development of lung metastasis, the size and number of metastatic lung nodules decreased and were not detected anymore after 14 months. Serum alpha-fetoprotein levels also decreased to normal range and no viable tumor was noted in the liver. The patient is still alive 12 years after the first diagnosis of HCC and 16 months after lung metastasis developed.

Reports of metastatic hepatocellular carcinoma (HCC) without a primary liver tumor are rare. Here we present a case of isolated HCC that had metastasized to the pelvic bone without a primary focus. A 73-year-old man presented with severe back and right-leg pain. Radiological examinations, including computed tomography (CT) and magnetic resonance imaging (MRI), revealed a huge mass on the pelvic bone (13x10 cm). He underwent an incisional biopsy, and the results of the subsequent histological examination were consistent with metastatic hepatocellular carcinoma. The tumor cells were positive for cytokeratin (AE1/AE3), hepatocyte paraffin 1, and glypican-3, and negative for CD56, chromogranin A, and synaptophysin on immunohistochemical staining. Examination of the liver by CT, MRI, positron-emission tomography scan, and angiography produced no evidence of a primary tumor. Radiotherapy and transarterial chemoembolization were performed on the pelvic bone, followed by systemic chemotherapy. These combination treatments resulted in tumor regression with necrotic changes. However, multiple lung metastases developed 1 year after the treatment, and the patient was treated with additional systemic chemotherapy.

Transcatheter arterial chemoembolization (TACE) has been used widely to treat patients with unresectable hepatocellular carcinoma. However, this method can induce various adverse events caused by necrosis of the tumor itself or damage to nontumor tissues. In particular, neurologic side effects such as cerebral infarction and paraplegia, although rare, may cause severe sequelae and permanent disability. Detailed information regarding the treatment process and prognosis associated with this procedure is not yet available. We experienced a case of paraplegia that occurred after conducting TACE through the intercostal artery to treat hepatocellular carcinoma that had metastasized to the rib. In this case, TACE was attempted to relieve severe bone pain, which had persisted even after palliative radiotherapy. A sudden impairment of sensory and motor functions after TACE developed in the trunk below the level of the sternum and in both lower extremities. The patient subsequently received steroid pulse therapy along with supportive care and continuous rehabilitation. At the time of discharge the patient had recovered sufficiently to enable him to walk by himself, although some paresthesia and spasticity remained.

Hepatoblastoma usually occurs in children under the age of 2 years, with very few cases reported in adults. We experienced a case of adult hepatoblastoma in a 36-year-old female with chronic hepatitis B . She had experienced sudden onset abdominal pain. Her serum alpha-fetoprotein level was markedly elevated, and abdominal CT showed a 9-cm mass with internal hemorrhage in the right hepatic lobe with hemoperitoneum, so an emergency hepatic central bisectionectomy was performed. The initial histologic examination revealed that the mass mimicked combined hepatocellular carcinoma and cholangiocarcinoma with spindle-cell metaplasia of the cholangiocarcinoma element. Follow-up abdominal CT performed 3 months later showed a 5.5-cm metastatic mass in the left subphrenic area. Laparoscopic splenectomy with mass excision was performed, and hepatoblastoma was confirmed histologically. A histologic re-examination of previously obtained surgical specimens also confirmed the presence of hepatoblastoma. Metastatic hepatoblastoma was found at multiple sites of the abdomen during follow-up, and so chemotherapy with cisplatin, 5-fluorouracil (5-FU), and vincristine was applied, followed by carboplatin and doxorubicin . Despite surgery and postoperative chemotherapy, she died 12 months after symptom onset.
