Fibrolamellar hepatocellular carcinoma (FLHCC) is an entity distinct from ordinary hepatocellular carcinoma and is very rare in Oriental countries. We present here a Japanese case of FLHCC in a 25 year old woman, and review Japanese cases of FLHCC. The patient had mild abdominal pain when the hepatic tumour was revealed by ultrasonography. Hepatitis B surface antigen (HBsAg) and anti-hepatitis C antibody were negative and serum alpha-fetoprotein (AFP) was within the normal limit. Ultrasound-guided fine needle biopsy was performed and the tumour was histologically diagnosed as FLHCC. A right lobectomy of the liver was then performed. Macroscopically, the tumour (10 x 10 x 8 cm) was circumscribed, rather hard and yellowish white. Microscopically, neoplastic hepatocytes were polygonal and large with eosinophilic cytoplasm, which contained pale bodies. A number of fibrous stroma were arranged in thin parallel bands. Consequently, the case was diagnosed as FLHCC. In Japan, approximately 18,000 people die of ordinary hepatocellular carcinoma annually, while only nine cases (including the present case; six males, three females) of FLHCC in Japanese subjects have been reported previously. The mean age of the Japanese cases of FLHCC is 20.9 years old. One case with positive HBsAg, liver cirrhosis and high level of AFP was observed of nine cases. The nature of FLHCC in Japanese subjects may not be significantly different from that in Caucasians, except for male predominance.

A 6-year-old Malay boy presented with fever and abdominal pain for 2 months. Computerised tomography showed a nodular mass in the left lobe of the liver. There was also portal vein thrombosis on the left side. Serum alpha-fetoprotein was not elevated and Hepatitis B antigen was negative. Biopsy of the liver mass led to a histological diagnosis of fibrolamellar hepatocellular carcinoma. In view of extensive tumour involvement, he could not be operated on but was treated with chemotherapy. However, the tumour did not respond. While this is expected for fibrolamellar hepatocellular carcinoma, the possibility of the tumour having a component of ordinary hepatocellular carcinoma could not be excluded as the tumour was not resected. Fibrolamellar hepatocellular carcinoma is a rare histological subtype of hepatocellular carcinoma, associated with a better prognosis. It affects the younger age group and has no association with cirrhosis, hepatitis B virus infection or exposure to oral contraceptives, all of which are implicated in ordinary hepatocellular carcinoma. Serum alpha-fetoprotein level is usually within normal limits and other laboratory values are not contributory to the diagnosis. The diagnosis is usually suggested by radiographic studies viz. CT scan of the abdomen, which would show an irregular non-homogenous mass in the liver, and confirmed by histological examination. The most characteristic microscopical feature is fibrosis arranged in a lamellar fashion around polygonal and deeply eosinophilic neoplastic hepatocytes.

Fibrolamellar hepatocellular carcinoma (FLC) is a rare histologic variant of hepatocellular carcinoma that appears most commonly in teenagers and young adults. The diagnosis is often made incidentally and surgical resection is the only curative treatment. Here we report two cases of incidental FLC involving a 19 year-old male, initially diagnosed with screening abdominal ultrasound, and a 14 year-old female that presented with abdominal pain. Diagnostic workup consisted of abdominal PET/CT and MR1 Imaging studies and tissue diagnosis was confirmed with percutaneous liver biopsy. Both patients were treated with radical liver resection/tumor excision. However, tumor recurrence was observed in both during short-term follow-up. The male patient was treated successfully with surgical treatment however the female patient succumbed top regression of disease.

Synchronic occurrence of benign and malignant tumors is extremely rare. Fibrolamellar hepatocellular carcinoma represents 1% to 2% of all hepatocarcinomas, while myxomas represent about half of all the cases of primary tumors of the heart. We present the case of a 53-year-old woman with a left atrial myxoma that was surgically removed. Several weeks later, the patient returned to the hospital with abdominal pain. CT scan showed a mass in the left lobe of the liver that was resected and diagnosed as fibrolamellar hepatocellular carcinoma. As of this writing, the patient is healthy.

Fibrolamellar hepatocellular carcinoma is a rare primary malignant liver neoplasm. Benefits from liver transplant for patients with fibrolamellar hepatocellular carcinoma have not yet been reported. Here, we report a 19-year-old female patient who presented with abdominal pain. A computed tomography scan revealed bilobar and multiple solid lesions with the largest measuring 15 cm in diameter on the right lobe of her liver. Her blood alpha-fetoprotein level and viral hepatitis markers were normal. A fine-needle biopsy of the largest lesion detected fibrolamellar heptocellular carcinoma. Because no distant metastasis was evident and the carcinoma was unresectable, a right lobe living-donor liver transplant with hilar lymph node dissection was performed. A pathology report revealed poorly differentiated fibrolamellar hepatocellular carcinoma, and further testing indicated microvascular invasion and hilar lymph node metastasis. The largest tumor measured 12 cm. She was discharged on postoperative day 14. During postoperative month 22, multiple vertebral metastases were detected, and she died with diffuse metastasis during postoperative month 26. Our patient, with poor prognostic criteria such as hilar lymph node metastasis, microvascular invasion, and poor differentiation, had 22 months of tumor-free survival and 26 months of overall survival after having undergone living-donor liver transplant.

Fibrolamellar hepatocellular carcinoma (FL-HCC) is a unique variant of hepatocellular carcinoma. The majority of cases present with nonspecific symptoms like vague abdominal pain, weight loss and fatigue. Ruptured FL-HCC occurs rarely and mortality in the acute phase is very high. We report a rare case of a ruptured FL-HCC successfully managed with transarterial embolization for hemostasis. A 37-year-old male previously in good health presented with a severe, sharp epigastric pain that started 1 h prior to the presentation. He denied trauma, fever, nausea, vomiting, or diarrhea. Tenderness in the epigastrium was noted, with no palpable masses, guarding or rigidity. His blood pressure and pulse were 159/105 mm Hg and 105 beats/min. Platelets and coagulation parameters were within normal limits; transaminases were elevated. Abdominal computed tomography (CT) scan with contrast revealed an 8 cm lobulated mass with central hypodensity in the left hepatic lobe with perilesional blood and free pelvic fluid, indicating tumor rupture. CT angiography showed tumor neovascularization from a branch of the left hepatic artery which was embolized using transarterial gelfoam. Liver magnetic resonance imaging (MRI) and biopsy were consistent with fibrolamellar variant hepatocellular carcinoma. After 4 days, as the symptoms resolved, and the lab results were stable, patient was discharged and underwent a left hepatectomy 3 weeks later. FL-HCC occurs commonly in the left lobe of a young and non-cirrhotic liver. Typically, cross sectional imaging reveals a lobulated mass with well-defined margins, areas of hypervascularity and a central calcified scar. Histologic appearance is characterized by eosinophilic polygonal shaped cells separated by lamellar fibrosis. Surgical resection is the treatment of choice with better outcome when compared to conventional HCC. Disease recurrence after complete surgical resection is however high in the first 5 years. Tumors > 5 cm in size are at high risk for rupture with high mortality and recurrence rates secondary to significant spillage of tumor. While an emergency hepatectomy is preferred in unstable patients, those that are hemodynamically stable can undergo radiologic transarterial embolization for hemostasis followed by staged hepatectomy.
