1/996. Intact PTH-producing hepatocellular carcinoma treated by transcatheter arterial embolization.We report a case of hepatocellular carcinoma with hypercalcemia. There was no evidence of bone metastasis or increase in parathyroid hormone-related protein. The serum level of intact parathyroid hormone (intact PTH) was very high, and the results of the hepatic venous sampling suggested that the tumor produced intact PTH. Transcatheter arterial chemoembolization effectively controlled the humoral hypercalcemia.- - - - - - - - - - ranking = 1keywords = hepatic (Clic here for more details about this article) |
2/996. Premalignant lesions and hepatocellular carcinoma in a non-cirrhotic alcoholic patient with iron overload and normal transferrin saturation.A 66-year-old white man had a hepatic resection for a 6-cm well-differentiated hepatocellular carcinoma which had developed in a non-cirrhotic liver. The only risk factors found were heavy drinking, smoking and heterozygosity for the C282Y mutation of the HFE gene. The liver was mildly fibrotic and overloaded with iron. It also contained numerous iron-free hepatocellular lesions from <1 to 10 mm, suggesting a premalignant change. These lesions were of three types: (i) iron-free foci, (ii) hyperplastic nodules and (iii) dysplastic nodules with severe dysplasia or even foci of well-differentiated grade I hepatocellular carcinoma. This observation suggests the possibility of malignant transformation of the liver in the newly-described syndrome of iron overload and normal transferrin saturation. It also illustrates the multistep process of carcinogenesis in the non-cirrhotic liver.- - - - - - - - - - ranking = 1keywords = hepatic (Clic here for more details about this article) |
3/996. Primary yolk sac tumour of the liver in adulthood.Primary yolk sac tumour of the liver is exceedingly rare. A 28 year old woman presented with a cystic liver mass and a markedly raised serum alpha-fetoprotein concentration. She underwent a partial hepatectomy for a suspected hepatocellular carcinoma but histological examination of the tumour revealed the classical morphological and immunohistochemical features of a yolk sac tumour. There was no evidence of an extrahepatic primary source. review of this case, together with the six previously reported adult cases of primary yolk sac tumours of the liver, revealed several features of the tumour that may aid differentiation from hepatocellular carcinoma, with potential therapeutic implications.- - - - - - - - - - ranking = 1keywords = hepatic (Clic here for more details about this article) |
4/996. Combined hepatocellular-cholangiocarcinoma. Diagnostic challenge in hepatic fine needle aspiration biopsy.OBJECTIVE: To study the cytohistologic features of combined hepatocellular-cholangiocarcinoma (CHCC-CC) in fine needle aspiration biopsy (FNAB) material. STUDY DESIGN: Six hepatic FNAB cases with cell blocks (five) and hepatic resections (two) were analyzed cytohistologically and immunohistochemically. RESULTS: The six cases were diagnosed as CHCC-CC based on clinicopathologic correlation. Unequivocal hepatocellular carcinoma (HCC) cells corresponding to Edmondson and Steiner's grade 3 lesions were identified in the FNAB in three instances. adenocarcinoma, represented by cohesive columnar cells with ovoid, basal nuclei displaying nuclear palisading, acini and/or papillary structures with variable intracytoplasmic intraacinar or brush border mucin production, was identified in all cases. Intermediate cells with hybrid/polymorphic cytologic features straddling malignant hepatocytes and glandular cells were identified in five instances. Tissue alpha-fetoprotein was negative. There was brush border and/or diffuse cytoplasmic p-carcinoembryonic antigen immunoreactivity in the glandular elements. CONCLUSION: FNAB diagnosis of CHCC-CC is possible if the clinical, cytohistologic and immunohistochemical findings support the presence of HCC and adenocarcinoma. Intermediate cells pose a great challenge to recognize and define: they tend to lose the classic cytologic features of malignant hepatocytes and acquire glandular characteristics. At the very least, there should be a high index of suspicion. These cases underscore the necessity for clinicopathologic correlation in enhancing the precision of FNAB diagnoses.- - - - - - - - - - ranking = 6keywords = hepatic (Clic here for more details about this article) |
5/996. Durable clinical and pathologic response of hepatocellular carcinoma to systemic and hepatic arterial administration of platinol, recombinant interferon alpha 2B, doxorubicin, and 5-fluorouracil: a communication.The case described here illustrates the antitumor activity of a four-drug systemic combination chemobiotherapy with platinol, recombinant interferon alpha 2b, doxorubicin (Adriamycin), and 5-fluorouracil (5-FU) (PIAF) in a patient with diffuse hepatocellular carcinoma involving the liver and lungs.- - - - - - - - - - ranking = 4keywords = hepatic (Clic here for more details about this article) |
6/996. Management of adrenal metastasis of hepatocellular carcinoma by asynchronous resection of bilateral adrenal glands.We report on a 65-year-old man who received asynchronous bilateral adrenalectomy for adrenal metastasis of hepatocellular carcinoma. Fifteen months after curative resection of right hepatic lobe for hepatocellular carcinoma, a metastatic lesion of the left adrenal gland was detected and left adrenalectomy was performed. Ten months after the second operation, a metastatic lesion in the right adrenal gland, associated with tumor thrombus in the inferior vena cava, was revealed. Transcatheter arterial embolization of the arteries feeding the metastatic tumor was performed, but its effects were incomplete. As there was the tumor thrombus in the inferior vena cava and no other intrahepatic recurrence or extrahepatic metastasis was found, resection of the right adrenal gland with tumor thrombus, without the employment of veno-venous bypass, was performed, followed by postoperative hormonal supplementation. Changes in the patient's alpha-fetoprotein level were clinically useful for the detection of the metastatic lesions and the evaluation of therapeutic effects. Metastasis to adrenal gland from hepatocellular carcinoma should be actively managed, and the appropriate surgical treatment selected, if intrahepatic recurrence and/or other extrahepatic metastasis are controlled. To achieve higher curability and better outcome in patients with bilateral adrenal metastasis of hepatocellular carcinoma, bilateral total adrenalectomy is indicated, accompanied by effective postoperative hormonal supplementation.- - - - - - - - - - ranking = 5keywords = hepatic (Clic here for more details about this article) |
7/996. Disappearance of gastric antral vascular ectasia after percutaneous transhepatic obliteration.We report on a patient with severe iron deficiency anemia due to gastric antral vascular ectasia (GAVE), complicating hepatocellular carcinoma (HCC) and esophageal varices. Esophago-gastro-duodenoscopy (EGDS) 6 months after transarterial embolization (TAE) for the HCC and percutaneous transhepatic obliteration (PTO) for esophageal varices, showed the absence of GAVE. As GAVE did not recur in spite of the recurrence of the tumor thrombus later, lowered antral congestion by PTO might be the main cause of disappearance of GAVE. This case suggests that PTO may be an effective treatment against GAVE with portal hypertension with uncontrollable bleeding.- - - - - - - - - - ranking = 5keywords = hepatic (Clic here for more details about this article) |
8/996. rupture of hepatocellular carcinoma after transcatheter arterial embolization: an unusual case.rupture of hepatocellular carcinoma (HCC) as a complication of transcatheter arterial embolization (TAE) is very rare. An unusual rupture of HCC after TAE was treated with successful surgical resection. A 65 year-old woman with liver cirrhosis developed multiple HCC in both lobes of the liver. TAE was attempted for the HCCs, but the original left hepatic artery, obliterated due to the previous repeated TAEs, was replaced by the left gastric artery. Right hepatic arteries were embolized while preserving the replaced left hepatic artery. Nine days after TAE, the patient presented a rupture of HCC in the left lateral segment of the liver, in which no deposit of Lipiodol was recognized. Since additional TAE to achieve hemostasis failed, left lateral segmentectomy was carried out with concern for the poor hepatic functional reserve. The patient was discharged 3 weeks after surgery without any complication. This is the first case of ruptured HCC in the non-embolized part of the liver after TAE, which was resected successfully.- - - - - - - - - - ranking = 4keywords = hepatic (Clic here for more details about this article) |
9/996. Extraosseous metastases of hepatocellular carcinoma detection and therapeutic assessment with Tc-99m PMT SPECT.Owing to recent advances in imaging technology and radiologic intervention, survival rates in patients with hepatocellular carcinoma have improved markedly. However, such prolonged survival has resulted in an increase in extrahepatic metastases. Tc-99m (Sn)-N-pyridoxyl-5-methyltryptophan (Tc-99m PMT), developed for hepatobiliary scintigraphy, has been used to visualize extrahepatic metastases, with most related reports limited to osseous metastases. The authors report two cases of hepatocellular cancer presenting as a hypopharyngeal metastasis and intraperitoneal dissemination along the tract of a fine-needle biopsy. Lesions undetectable on planar imaging could be visualized by Tc-99m PMT SPECT.- - - - - - - - - - ranking = 2keywords = hepatic (Clic here for more details about this article) |
